In Japan of 1992, just after the economic bubble burst, society's public safety began to deteriorate. Xu Tianze finds himself transmigrated into the body of a detective named Aoyama Hidenobu, and the moment he opens his eyes, he discovers himself bound up tightly...Entering the new century, a prestigious magazine proclaimed that although Japan has lost a decade since the 90s, they gained a legendary figure like Aoyama Hidenobu.Regarding this, some Japanese nationals expressed: 'Damn it! We'd rather lose another 100 years than have this traitor to our country!'This book is also known as 'This Tokyo is Somewhat Hot.'PS: The protagonist is a rascal, acting with contempt, decisive in killing and fighting, purely for the thrill, not for the faint-hearted.

When MC was reliving a picture of a goddess, he died. Only meet the goddess, but instead of torturing him to eternity, she gives him wishes. And make him reincarnated in the Overlord world.As the name suggested, this is multiverse Fan fiction, that means MC will travel through different world like Marvel, DC, High School DXD, My vampire Diaries (may be) , Demon Slayer, etc.first world: Overlord (Chapter: 1—60)second World: Highschool DXD (Chapter: 60—215)Third World: Demon Slayer(Chapter: 216—)Fourth World: New World (Overlord)There will be a harem, no NTR or stuff.Some of you might dislike the Yggdrisil arc as it is a bit of AU and MC talk a lot. But it is only in this arc on world travel that I will tone down his unnecessary internal monologue.I am not a professional writer, and I have no deep experience in writing, so please ignore my grammar mistakes and such. I also took some inspiration from other fan fiction.It would be a great help if you could donate your power stone to me.
