Ichirō Shinjō

Ichiro Shinjo is a Junior, Captain of the Boxing Club, and because of his rank in the club, he is a member of the Rokkisei- the Six Horsemen.

He is a second-year at Saint Ishiyama High with light wavy hair. At first, he shows contempt for Ishiyama's students and seeks a confrontation with Oga in the first opportunity. At the point, Oga's thoughts are of forcing baby Beel on him; knowing that fighting back means expulsion, he decides to take his punches at first, while testing him with trivia questions in order to show baby Beel that Shinjou Alex is not only strong but clever, with comic effect.

Abilities
The captain of the boxing club, he is regarded as the second best high school boxer in the nation and is known to finish all matches with a one-hit knockout of the opponent. Alex is strong enough to defeat the MK5 with ease. However, he is no match for Oga: his punches fail to knock him out at first; later, Oga easily evades them and even stops one with his hand. When he finally evokes a reaction from Oga, the latter deals him a defeat similar to the ones Alex is known to deal to others: a one-hit knockout.
