La Historia esta siendo Reescrita, lamento las molestias, cuando los nuevos capítulos estén listos reemplazaran los viejos o tal vez publique otra versión.

A human soul’s life in an unknown fantasy world filled with mysteries and danger began. Can't fit the whole synopsis in this (the limit is 300 or so characters), so please make do with the last line xD.

In the supernatural world, so many things exist. But reincarnation into it with an ability called 'The Gamer' is unheard of. As if to make things more interesting, a Dragon is thrown into the loop. And so began the adventures of 'The Dragon Gamer' with his Dragon partner and a broken system. And what is this about my race change?

Issei fills out a mindless coombrain fantasy CYOA, gets the powers, and the Editor is dead so he can just get his dick wet. He gets his dick wet. Also, there's demons and angels and such, but he doesn't know that, so he mostly focuses on getting his dick wet at first.

Being the son of Tiamat came with a lot of expectations that Emrys was confident in living up to the hype. Now all he has to do is find his dad to collect some child support. OC/Lemons

I'm not good with summary but this is a forbidden love story between an angel who has fallen and a devil

On one hand, being reincarnated with an admittedly lackluster System is a dream come true. On the other hand, being thrown into the middle of a Civil War isn't exactly the best start to an Isekai adventure. (GamerSI-OC) (GamerxHarem)

A new man got hired for a teaching job. He seems nice.

Yamaguchi Ryuichi, discovered a mysterious app installed on his smartphone. Due to the existence of the app, his ordinary and flat life has now changed 180%. An ordinary man, but not ordinary when you get to know him more closely. I'm a sucker for doujin plots. Don't expect too much from the plot, because I just want to express my wild fantasies.

Current ongoing story: The Apathetic Heir. Gamer Si, grey/dark mc, harem. Devil heir. Essence cyoa.

"One day, I opened my eyes, and found myself vomiting off the top of the mountain. Definitely not the best way to start my day, or evening at that point. Then I got attacked by a mutated snake, taken in by a perverted virgin kitty, and went back home to get blown up by a dragon. Twice. And that's only the start. At least it's exciting? This new life of mine." (Demigod SI-OC)

In light of recent events, Blacklight - an organization whose job is to eliminate threats from both man and the Moonlit World - dispatched its newest operative at the request of one of the Three Factions.

After numerous sightings of missing people in Kuou, I find myself tasked with investigating and uncovering the truth about these events. Now, Reinhardt, Ana, and I are part of the city's academy as we search for answers to this mystery. Only perhaps making a deal with demons doesn't sound so bad. Harem
