Jumpin' Jack' Jolted

In the school hallway, Keigo and Mizuiro speculate about Ichigo's absence before finding their classroom wrecked and a furious Tatsuki standing amid the debris. A teacher doubts the students' account of a third-floor intruder until Ryō corroborates it, and Orihime insists the culprit was not really Ichigo. Meanwhile, Ichigo frets over Kon kissing Orihime in public, and Rukia realizes his rough appearance is deliberately maintained.

Rukia explains that Kon is a modified soul from the abandoned Project Spearhead, which sought to place combat spirits into corpses to fight Hollows by supercharging part of the host's body; Kon's enhanced legs mark him an Underpod type. The project was scrapped as immoral, and its creations were ordered destroyed, though Kon somehow survived. Ichigo questions whether it is right to condemn Kon merely for being what Soul Society made him, but Rukia maintains the law exists to protect humans and souls.

Kon bounds through the streets soaking up attention, then leaps a tall wall near the elementary school, seen by Yuzu and Karin, who silences a witness and warns Yuzu to stay quiet. Perched by a shed, Kon overhears three boys casually discussing deleting a disobedient video game character, declaring that anything that will not obey its master should die, which visibly disturbs him. At the Urahara Shop, Urahara comforts a guilt-ridden Ururu and orders his staff to begin Operation Recall.

The origin of modified souls in Project Spearhead is explained, framing Kon as a condemned survivor. Kon overhears children carelessly discussing deleting a game character, echoing his own sentence of destruction, as Urahara mobilizes to recapture him.

This chapter of the second volume and the Agent of the Shinigami arc deepens the modified soul concept and Kon's plight. It was adapted into the anime's sixth episode, Fight to the Death! Ichigo vs. Ichigo. Viz Media titles it Jumpin' Jack, Jolted.
