I wanna be like near from death note how?

[Henry]

Like I wanna investigate without anyone knowing me, honestly I don't really have emotion, I solve 3k puzzles in a day and a half from boredom

So become an anonymous detective. Find unsolved crimes and try to solve them yourself from your house. Refer to yourself with an alias (Near, N, L), and if you actually find something, send it to Crime Stoppers. You should create an alternate Email. Play with toys while you do it.

Dye your hair white
Wear all white
Become an orphan
Go to Wammy's house
Study under L
Change your name to Nate Rivers
Become essentially a genius
Play with toys

That covers the basics, sort of.
