Crim Kenju

Crim Kenju is the heir to the elusive Kenju Clan and a Genin of Konohagakure. He is known in his generation as the Master of Kenjutsu, also known by many of the young Genin of Konohagakure under a different name, "Crim, the Blue Flame Swordsman." As talented as he may be in Kenjutsu, this isn't only thing he is known for. Crim is also quite proficient in Fire Release, sparking the unique Kekkei Genkai, Blue Flame Release. With this ability, he can freely mend Blue Fire at will, hence his title.
