Kyogre: You're the God of the Ocean, So What Am I?

(Pokemon fan + reborn as an egg + becomes a Shiny Wishiwashi + never turns human + has a younger sister + CP is Dratini, which evolves later; not a Green Fat Dragon)

To clarify: This is a modern Pokemon Blue Star. The protagonist has a System with the special ability to enter the Pokemon world from the anime, where he befriends Ash.

This book is also known as "Am I Really Weak as a Wishiwashi?"

Dear readers,

I'm a new author, and I'm meeting you all with a mix of nervousness and excitement.
