I want help with writing the story

As the title says, I want help and because I'm a relatively bad writer (I think), I feel that I won't be able to write a story that sounds good. Because of that, I would like to have someone else write it for me or at least give me feedback. I should also mention that the story idea would probably fit better as a comic/manga but I can't draw that well.

The story itself is a little bit of a parody of battle shounen (and other animes too). Like in many battle shounens, many characters transform to get stronger and the power system in my story is basically a parody on that. Everyone can transform to get stronger (however most people can only do it once). Everyone has different powers, like someone can transform into a magical girl, somebody else can transform into a dragon and another person might just get stronger abilities.

People usually use their powers to protect or fight against the swarms of demons from another dimension that constantly attack the planet. However they do only attack towns and only each town a few times per year. Most demons are also weak so it isn't that common for people getting serious injuries.

Then the actual story might be a bit complicated to explain but I will try anyway. Note that nothing is set in stone yet and I won't explain everything because it would take too long (but it will be a bit long anyway). I will talk about major spoilers but I will give early story description of the main characters first and those are:

* The protagonist of the story is a teenage(?) boy nicknamed Speed. He has the power of "Speed" but can't activate his power when he wants to. About one year ago he woke up without any memories about who he is. He did get some help and started to go to high school but he has been unable to find out who he is. Also during the last year, two of the people Speed trusted the most tried to kill him. After that he became paranoid and stopped trusting in others but sometimes his "emotions" say something different than his "logic".

* Homura, who is the heroine of the story. She has the power of "Fire" but can't transform so she always too weak to fight. After Speed saved her once she became interested in Speed and started to try to get to know Speed better. However Speed tries to avoid her because he thinks Homura is one of them who tries to kill him, even though that he felt like he fell in love with her at first sight. Then after she learns what have happen to Speed she tries to help Speed to learn to trust others again.

* Ryuu, who has the power of "Dragon" however he doesn't get that much stronger even though he transforms multiple times. However it wasn't always like that. When he was a kid he didn't have that problem but after his hometown got destroyed by a certain demon in front of his eyes he started to have that problem. He doesn't remember why. He is also the son of Reiku, the only person that could transform 10 times but he disappeared then the town got destroyed.

* Koneko, who has the power of "Cat" but is too scared to fight the demons. She is a second cousin with Homura and they have been friends for as long as they can remember. She has a shy personality but she loves to eat meat. In school she usually wears a big hoodie and in the hood she has a kitten which she calls Nekoshi.

*Kenshi, who has the power of "Swordman" and is the strongest student in the school but has barely gotten stronger for the last year. For some reason he has to get even stronger and because of that he skips school often just to train. He often starts fights just to prove that he is the strongest but he can't beat Speed because Speed just dodge his attacks so Kenshi sees Speed as a big obstacle to his goal of becoming the strongest.

SPOILERS from this point forward.

50 years ago (which would be during our time if the story would take place in "our" world) everyone got superpowers at about the same time for a certain reason which almost no one knows. Shortly after that the demons appeared and started attacking the planet.. People started to panic but some started to use their new powers to fight the demons to protect their homes.

However, for several years after that, people weren't really allowed to use their powers (however there were differences between countries' rules/laws) and usually only the military was allowed to fight the demons. However, at around 35 years ago kids started to get allowed to train their powers to fight the demons because people agreed that most civilians can defend themselves if they use their superpowers.

Because the kids were allowed to train their superpowers, they became stronger than the previous generation. Then 17 years ago, the twins Hori and Pori got kidnapped by the Demon King because they had the power of "Holy Light Healing". The Demon King who is weak against the "holy" attribute thought he could use them to make an heir that doesn't have his weakness and who also has the healing ability.

In order to save the twins and also trying to stop demons for good, about 2000 of the strongest people of the world went to the demon's world. The person who was assigned to lead everyone was Kiritsu, a young woman with a superpower they called "Princess" (however "Queen" would be more correct). She was one of only three in the world that can transform 10 times (but people just remember one). The others was, Kiritsu partner Ken who has the power of "Knight" and Reiku who has the power of "Dragon".

The attack on the demons was a half success. They were able to defeat the Demon King with Reiku dealing the final blow which only left the Demon King as a pile of bones. Then they were able to save the twins however only 21 were able to return alive and the attacks from the demons didn't stop but they became weaker.

While most of them who died were killed by demons, Kiritsu intentionally gave bad orders so they would die because she had made a deal with the demons before the attack. I won't go into detail why she made the deal but she did that to protect the world.

A while after Hori and Pori were saved, they noticed that they got pregnant. They went through the pregnancy and Hori gave birth to triplets and Pori twins. The children looked like normal babies even though they were the children of the Demon King. The triples were two girls and one boy. They got the names Homura, Hikari and Kurai.

As Homura and Hikari grew up they became close with their neighbor Sokudo (who is the protagonist Speed), a boy who was 6 years older than them. Then one day 6 years ago they confessed to Sokudo that they loved him. He liked them too but he thought they were too young so he said they have to wait until they get older. Homura and Hikari became sad and ran away out on the road.

At that moment a truck came from nowhere and Sokudo saw that so he ran while using his power of "Speed" to save them and pushed them off the road so the truck wouldn't hit them but he couldn't save himself and died after being hit by the truck. From that moment they decided they would train their powers so they could maybe revive Sokudo.

A few months later, Homura, Koneko, Ryuu and Kenshi with their families were at a hill a bit outside of town. However after a certain thing happened, Homura transformed to her demon form for the first time. Ryuu saw her transform and recognized by her demon form that she was the daughter of the Demon King. Ryuu attacked her with his strongest attack because he wants to protect the world.

Homura was powerful enough that she didn't get that hurt but the attack continued past her and hit the town. The attack was so powerful that the whole town just became a huge crater. Ryuu became so traumatized by what happened that he forgot what happened and then he started to unconsciously hold his power back.

2 years ago, 4 years after Sokudo died, Homura and Hikari were able to revive him however without his soul and his heart didn't start so Homura took out her heart and put it in Sokudo. Homura healed herself and "made" a new heart for herself. None of them knew that souls exist and the only thing Homura and Hikari noticed was different with the revived Sokudo was that he was unable to activate his powers when he wanted but that didn't disturb them. They were just happy that Sokudo was back.

Then one year later when Sokudo, Homura and Hikari were out during a demon attack, Kishi, son of Kiritsu and Ken stopped them and sealed Sokudo's memories (but not his emotions related to those memories). The girls became cautious because they don't know how Kishi power works. They thought if they would fight him they would risk never getting Sokudo's memories back. Then did Kishi slice off some of the girls’ limbs to immobilize them. They started to scream and the nearby demons who heard them understood that they were the daughters of the Demon King so they went and saved Homura and Hikari.

The demons sent them to the demon's world to recover, however Homura and Hikari have really good healing ability so they didn't really need help. They wanted to return home as fast as possible however the demons didn't let them leave. They wanted at least one of the girls to become the new ruler of the demons. However if they would make an heir they would be allowed to leave. After talking for a while Hikari became the Demon Queen and Homura would make the heir with the Demon Lord, currently the strongest demon.

Then the prologue starts with Sokudo waking up without any memories about who he is. He gets the nickname Speed because of his superpower. After a while he starts in high school and meets a girl named Eirian. He becomes close friends with her but one day she tried to kill Speed but Speed's power activated on its own which saved him. However for the others who were around for the incident, it looked like Speed was an "asshole".

Speed became hated by almost everyone in school but the school nurse Mata believed him. However she also tries then to kill him too but with drugs however Speed's power activated again on its own so he was able to avoid the drugs. After that Speeds lost his trust in others and tried to be alone as much as possible but he continued to go to school.

In the demon's world (which won’t be in the prologue), Homura was able to make an heir so she was able to leave but she had to come back regularly. However Hikari had heard from the demons what was outside the demon's land and she wanted to explore it. The demon's world was actually a fantasy world so she thought it would be fun to travel a world of sword and magic.

However, one thing Hikari didn't think she would find was Sokudo (with his soul which makes this Sokudo the real one. The other one is actually more of a copy). Sokudo was summoned to this world to fight the new Demon Queen (Hikari). Hikari decided that she wouldn't tell Homura about this Sokudo so she could have him for herself.

The actual story starts shortly before the new school year starts. During a demon attack, Speed sees Homura being hunted by demons (but she just pretends). She shot small fireballs at the demons but that had no effect on them. Speed doesn't remember Homura but when he saw her it felt like love at first sight for him. Speed thinks at first that he should just ignore her because she would probably try to kill him too, however he feels bad ignoring her so he tries to save her.

At that moment his superpower activated when he wanted so he rushed to Homura and saved her from the demons. Homura had decided to act like she didn't know Speed because if she said that she was his girlfriend when they just met, Speed might deny it. So she tries to rebuild their relationship over time instead and starts to act like she started to like Speed when he saved her.

When the new school year starts Speed learns that Homura started to go to the same school as him. Then Speed had to join the new "Power Problem" club for students that have trouble with their powers. The members are Speed, Homura, Koneko, Ryuu, Kenshi and also Nekoshi (which would be revealed later in the story). Nekoshi is actually Koneko's big brother who likes to pretend to be a cat.

With all the main characters together they would try to help each other and in the end of the story they (or at least some of them) become some of the strongest people in the world. Speed would be so fast that he could run at almost the speed of light (which he could technically do already at the beginning of the story).

Homura would be so strong that she would be able to destroy the sun even when she doesn't transform. She would also be able to destroy the universe if she transformed to her most powerful form. She was also this strong at the beginning of the story but she would only transform if she had to because she would feel so much pain it would kill a normal person.

Ryuu would be able to transform 10 times and would become even stronger than his father. Kenshi would have learned that he can summon more than one sword at a time and also that he can summon it anywhere he wants, even inside objects. Koneko would be so strong that she could slash through even the higher ranked demons and Nekoshi would be the same as her.

I think I will end the explanation of the story here. Comment if you are interested or send me a message on Discord. My name there is: antsan993
