Are there any urban novels that only have one main character playing with supernatural powers or cultivating?

Cover not mine (c) Yushiba Miyabi This is the story where Urahara Kisuke died after Nel failed to save him inside Askin's Gift Ball Delux and reincarnated in the world of DxD. I am not sure if I can capture Urahara's character properly so I apologize in advance if you are not satisfied. Also, English is not my native language. ++++++++++++++++++++++++ DISCLAIMER ++++++++++++++++++++++++ I don't own any of the characters from the canon. Please support the original work. ++++++++++++++++++++++++ Buy me a coffee Ko-fi.com/goyya00 patreon.com/goyya00

A dude in MHA with Madara Uchiha powers. Don’t take this seriously I’ve literally never in my life written a story before. Again DONT TAKE IT SERIOUSLY. Take it as one of those novels that’s so garbage, but you have absolutely nothing to read so you read it anyways. I’m very bored in quarantine with nothing to do. Also don’t expect so many updates because I’ll only update when I actually feel like it. I’m a very lazy person [Cover title made by this awesome dude named RISE10]

"Game user confirmation." -Currently game user : 1 "……." The 1 person the system mentions is me. That is how I could tell that this game will fail as well……. Juyeong Hong enjoys playing games more than anyone else, and is captivated by one which yields as much as the effort he puts into it, unlike his studies, where he has made no progress no matter the effort. Juyeong has bet nearly his entire life on the game and applies to be a beta tester. He is accepted for the game “Forgotten Legend” which has not been officially launched. Juyeong played with more effort than anyone and had a lot of fun, but there were seemingly no other players who had enjoyed it, so the game disappeared without a trace. Only three closed beta tests had been done ……. Moreover, the last closed beta test involved Juyeong Hong only. Then one day, the game returned, under a new title “Revival Legend.” Then suddenly, for some unknown reason, top companies around the world begin wanting to own the rights …

Bell Cranel was rejected by every familia he tried to join until he met Hestia. In a few, he was rejected quite violently. And in one particular instance, he was thrown out and bashed his head against a wall. Well, that's apparently where I come in. Not sure how and why I'm here. Not even sure who 'I' really am at this point since Bell's memories are definitely clearer than 'mine'... But I guess we're doing this. Hopefully I've got some useful cheats. Maybe?

A young man wakes up on an island with no memories of himself or his loved ones. All he has are memories not related to his personal life and a message introducing him to his new life. A few notes before you read this Fanfic. It's not going to be a rushed story. It's going to take time and go through things slowly. One Piece world only, no world traveling. While the Main Character will be strong, he will not be OP for quite a while. Be prepared to wait for it. The story will be following Luffy and the others for a while. This is for two reasons, one it helps me write and two, the Main Character actually has a valid motivation for doing so. No harem. Yes, the System is loosely based on 'The Gamer' but isn't a direct copy and is modified to suit my needs for my story. So while it might seem similar it is NOT the same. I do not own One Piece or any of the characters. All rights belong to their respective owners. I only own the Original Character. Prerelease Chapters here: patreon.com/playingnovels
