Yeah man, he's A KIRA (A Killer) and he's gonna kurusu/korosu(KILL) you. High five and all that for the one who came up with the name.
Tbh i read it as 'bright cross'. His name in kanji is 来栖 暁 which i'd roughly translate as "vessel of dawn"(first kanji means "future", second one "nest" third one "dawn") but akira also mean making thinks clear, so i liked to read it as someone who was cruxified for something they didn't do because well, kurusu means cross :T
Japanese names are weird, but it never crossed my mind the "killer" thing, I guess I'm too weeb for that.
I called mine "Seigino Tsubasa"(last name first name) which means wings of justice, because i'm tacky af
Edit: better translation for akira kurusu i hadn't thought of before: "bringer of light to the den", thanks reddit
