Synopsis

Quote:

Touno Hifumi learned various martial arts and discipline from childhood. One day, he was summoned to another world. Hifumi, who was suppressing his desire to kill people in modern Japan, decided to continue living in a different world. A human being who was forged in martial art to his limits, with a distorted sense of ethics, kills people without a second thought, has been called to a different world.

I tried looking for a thread for this but didn't find any. There's 13+ chapters released so far and it's been updated fairly frequently with over 140+ chapters publishing. The first chapter (titled 'Flip The Switch' I believe) really got this going and showed us what the MC can do. He is quite OP and the main female character is plenty strong herself too.
