You're not my match!

King Battler Jr., usually known as J, is a major character in the Sakigake!! Otokojuku series. He is initially introduced as an exchange student from Annapolis Academy, but quickly enrolls at Otokojuku after a boxing match with Momotaro. He is a skilled boxer and the son of legendary boxer King Battler.

Appearance Edit

J has short-cropped blond hair and stern facial features. He usually wears knuckle dusters made of an alloy he calls magnum steel. In his initial introduction, he wears an army green vest and pants, but after enrolling at Otokojuku, he wears a standard Otokojuku uniform, which is depicted as grey in the anime.

During his brief appearance in Sora Yori Takaku, J wears a white US Navy uniform, with his Otokojuku uniform jacket draped over his shoulders. He wears the same uniform in Akatsuki!! Otokojuku, but without the jacket.

J is very calm and stoic, even in the most vile and hellish situations. He can, however, display frustration on occasion. He appears to be the only current American in the Otokojuku team. He gained respect for Tsurugi Momotaro after the Otokojuku boxing match.

Powers and AbilitiesEdit


J is a high-level boxer who is able to perform the following techniques:

Mach Punch: J's signature technique. His punches move so fast that they break the sound barrier.

Ring of Crime: J delivers a punch to a single opponent among a number of opponents standing in a circle, which causes the rest of the opponents to fall over from the Domino effect. Though originally a form of punishment at Annapolis Academy, J retools this to be used in combat.

Hell's Dance: J's footwork allows him to move faster than the eye can follow.

Jet Sonic Mach Punch: A Mach Punch that causes a shockwave, allowing him to attack from a distance.

Flash Piston Mach Punch: A legendary boxing technique where one performs ten punches in under a second. Though legend has it that the strain on the boxer's arm is so great that arm is permanently disabled, J is able to overcome this and use it as his finisher.

Flying Crash Megaton Punch: A right thrown at the ground from mid-jump, powerful enough to destroy the ground beneath him.

Spiral Hurricane Punch: A punch with enough force to cause a whirlwind, only usable when J's body and mind are at their limits.

Triple Blade Jab Special: A self-sacrificial triple jab.

Fist of Fury: J's anger allows him to throw a punch with 100% of his body's potential.

Corner of Dead End: A high-level boxing technique in which J lures his opponent into the corner to restrict their footwork, then uses the recoil of the ropes to deliver a table-turning punch.


Major Battles Edit


In Akatsuki!! Otokojuku, J makes an appearance as the USAF Commander-in-Chief, or the President. However, his explicit title as Commander-in-Chief may not imply that he has become the President of the US: it may either be a misinterpretation by Miyashita or simply an emphasis on his military title.
