A 15-year-old male. A ninja apprentice during the Muromachi period. A sixth-year student at Ninjutsu Academy, the highest grade, and the chairman of the Etiquette Committee. He is highly skilled in ninjutsu and proficient with gunpowder, using fire arrows (horokuhishi) as his primary weapon. He has the best academic record in his grade and the coolest personality, though he is terrifying when angry. Despite his cold and composed demeanor earning him the nickname "The Young Noble," he is often driven to wit's end by his juniors. He has fair skin, sharp eyes, and long purple hair tied in a ponytail, which is exceptionally silky. He takes great pride in his hair. As a handsome young man, he is the most popular among the village girls. He wears a green ninja uniform. While he is naturally gifted in ninjutsu, he lacks significant muscle mass, though he remains formidable regardless. He is frequently subjected to all sorts of unfair situations and mishaps caused by his juniors until he is practically broken, but because he has a kind heart and truly cares for them, he continues to look after them. However, these situations usually end with Senzo losing his temper and throwing fire arrows everywhere in an explosive finale... Because of this, he often shows a short-fused side. He is usually cool-headed but has a slightly impatient streak and a bit of narcissism. He seems to be somewhat weak to compliments. Contrary to his appearance, he is not as organized as one might think and tends to let his laundry pile up.
