Hikoichi

Hikoichi (ヒコイチ) is a minor Skill-Out thug introduced in Toaru Kagaku no Railgun. His rugged boss runs a small Skill-Out territory in School District 7.

Appearance
Skinny and shown to be wearing a hoody, his appearance dramatically changes in the transition from manga to anime adaptation. In the original manga, strands of his hair had been made to stand on its end, giving him an extremely spiky haired look. In the anime adaptation, it is instead replaced by an afro.

Sisters Arc
He is first introduced as reporting his comrades in seeing Nunotaba Shinobu dropping the purported cash cards in alley and followed her. Seeing her alone, he tells his comrades that they should go get her.

He is the one who introduces the gang to Shinobu and is the one who takes her bag from her, believing that she may use an anti-crime buzzer. He is taken into the rouse by Shinobu after being touched by her after seeing that their comrade, Satoshi has been felled for reasons unknown. He is later felled by Shinobu's Critical ability, though he was just shocked to the point of being fainted due to Shinobu's excellent acting.

In the anime adaptation, he instead touches Shinobu as she reaches for her bag (for the anesthetic), and instead of Tetsu showing his doubts on fighting back against her, Hikoichi instead divulges his doubt to their boss. He is also felled in the dark by Shinobu, though through the use of the anesthetic.

He is later saved by Misaka Mikoto after Shinobu attempts to burn the building down.
