My review cannot do this story the justice it deserves
The story is about loss, memory, harmony and, most importantly the strength of sheer words (come on, it's a story about calligraphy)
Though calling it a story about calligraphy is an understatement, it's called Inkjutsu. What really had me invested was that force or power was not dealt with in the traditional shonen fights; rather, the fights were highly philosophical.

The characters were all interesting, and their development was well paced. I will go through the prominent characters
Kage: being the mc who was boring in the start but ended up quite a likable person
Yuki: Hairpin lady, perfect best girl (love you, Epti 0v0)
Mr Kage: a sensible antagonist who wants to eradicate emotions and hates empathy

I did my best with this review; please read the story to know why I am calling it a great work.
