Egor Lynch?

The billionaire, who has repeatedly ruined Lynch's life, always shows up at the most inopportune moments. He'll always help, but the price will be steep. He has personal security, a portal, and, most importantly, a Death Note.

Lily's son, Uncle Lynch, always tries to be like him, but he doesn't always succeed. He already saved his mother from a maniac, and saved his uncle in a snowman case. He has two best friends, he always goes for walks with them, and when Lily doesn't allow him to go for a walk, he always finds a way to escape, but because of this, Lily constantly punishes him.

Lynch's older sister, who has a son, Lucas, is a single mother. Lily constantly scolds Lucas for not getting into his room, which constantly upsets Lucas. John constantly makes advances towards Lily, but she brushes him off. Lily constantly takes care of Lucas, even when he doesn't ask.

Lynch's cousin, he travels through time; Lynch last saw him in action with the 2066 meter. Bolton, like Lynch, fights all manner of evil. Lynch inherited a house from Bolton that has a portal, but it doesn't fully function.
Almost nothing is known about Bolton, it’s not even clear whether he’s alive?

I have a best friend named Lynch, he's a writer who hasn't written a single book.👀
John constantly likes to go to KFC for wings, which is why he's always late. John is constantly hanging around... It seems he still can't accept the fact that he's a vampire. Animals are wary of John because he's a vampire. He constantly goes with Lynch on various missions, and he always helps him in any situation, no matter the scale of the problem.

John's best friend, they've been friends since 2018. Lynch is a journalist who's always cracking up with his camera, though you can hardly call him a journalist. Together with John, they fear evil and have saved humanity more than once.
He has an older sister, Lily, and a 14-year-old nephew, Lucas, and he constantly carries a camera around with him; he wants to be like his uncle. Lynch takes John on almost all of his assignments. Lynch values ​​their friendship.
