Tried out these 2 series, which started this week on Manga Plus
Since the government announced the existence of people with "special powers" 10 years ago, Susumu Shindou has longed for his own amazing abilities. However, he finds himself to be nothing but an average 15-year-old. Then one day, during his high school entrance ceremony, a power finally awakens...

Can a legendary assassin redo his life as a middle schooler?!

Vibration Man as a title is
.Pretty generic first chapter. Basically tries to have you make feel bad for the hero cause his poweer is useless. (Either does nothing or causes mass destruction) But could be decent if it improves from this point.
Kill Blue is basically a legendary assassin gentically turns back into a kid. Basically dude is going to middle school when he only passed elementary school. Could be interesting. I liked some of the comedy bits of an old man fitting in with the young crowd like this page.
The former feels like something I will give 10 chapters or so but wouldn't be surprised if I drop it.
The latter did give me a better impression tho it feels like it is going to be a mix of genres with the setup they are going with.
