Previous articles talked about how Akira Kurusu was a play on Protagonist and/or main character, but those articles have been long since covered by Google's search history, and I am not proficient in japanese to know how, or why, it's a play on words. I also think Akira just sounds badassSo i attempted to look it up, im probably wrong bur from what i can tell the name can mean "vessel of the dawn", or if you wanna take it in a literal sense, "a killer kill".
