Reincarnated As A Princess But I’m Still A Seal?!

Soru is your average seal or at least, until she died protecting her sister from a killer whale attack. When she opened her eyes, she became a princess just like she wanted. It's time to enjoy that bougie life! But wait... why do I still have a tail? If anyone finds out, I'm probably going to get murdered because of witchcraft probably! Why do I have to live in danger again?!

I am a seal and this is probably not a self-insert.
