Not sure what the deal with the flower is... but otherwise, best protagonist in the Shin Megami Tensei series... and one of the most kickass main characters in console RPGs period.

This guy needs a tag but seems to go by two names. Naoki Kashima in the CD dramas and Shin Mana in a novel by Toumon Boogey.

So what do you people think? Should we start tagging this guy as Naoki Kashima or just Demi-Fiend?

He also goes by the name "Hitoshura," which I believe is simply Demi-Fiend in Japanese. Hitoshura is the most common name for him that I've seen.
