One Piece: Reborn in One Piece as The Reincarnation of The Creator?!

The One-Piece plot won't focus on Luffy, so sorry about that!
English is also not the most proficient language to me so, if someone finds some parts to be very bad, just tell me and I will fix it and see if I can make it sound much better.
------------> One Piece does not belong to me as, One-Piece belongs to Eiichiro Oda. (Mc/Oc belongs to yours truly)
*Also, to diffuse the confusion about having a Harem, there won't be one. As the MC is bad with women.

Getting shot on your couch sucks would've suck, I mean come on! I would've watch some CoryXKenshin right now, if I'm not been given a chance to avoid getting shot and be forced into some anime world.
For some odd reason, everything is not making sense to me at all, why would an Entity choose to become my system in the first place?!

Follow the protagonist 'Cerise Star' on his adventures in One Piece with his "system" 'GL'.
