Devouring King /Queen

I am a newbie author and would like to see my imagination in a book.. SORRY If Synopsis is not good
The Mc will travel to Different worlds and I will create my own World to end it in

Please comment so I can improve my style

My MC WILL BE OP BUT HE/SHE WILL WORK HARD FOR IT

WARNING**: THE MC WILL CHANGE GENDER SO THERE WILL BE A LOT OF MATURE CONTENT LIKE NORMAL S*X AND YURI, THERE MIGHT BE BL IF READERS WANT IT

THERE WILL ALSO BE JAPANESE THINGS LIKE (SAN,KUN,SAMA,ETC.)

THANK YOU VERY MUCH
