JCC Transfer Exams Arc

This is the fourth story arc of the Sakamoto Days series, running from chapter 55 to chapter 72 across volumes 7 to 9 and adapted as anime episodes 16 through 22. Seeking deeper intelligence on Slur, Sakamoto and Shin disguise themselves as students and enter the JCC's admissions test, a trial that surrounds them with a fresh wave of deadly hopefuls.

Needing more information on Slur, Sakamoto and Shin pass themselves off as students and sit the JCC's entrance examination. The test drops them into a run of trials against fellow candidates and proctors alike, and the two must fight their way through while keeping their real purpose hidden.

The examination throws them against a string of opponents, from Shin's bout with Mafuyu to team battles that pull in Akira, Jay Erk, Kaji, Toramaru, and Usami, building toward confrontations with the deceptive Shinaya, who is revealed to be the deadly Gaku in disguise.

The arc floods the cast with new faces, formally bringing in Rion Akao and her niece Akira, along with Mafuyu, Jay Erk, Toramaru, and Kaji. Kanaguri is properly named and exposed as a member of the Order who secretly serves Slur, and Carolina Reaper enters the picture as well. Akira's talents are put on display, and Rion is established as an old friend of Sakamoto.

Reeling from the botched strike on the association and Uda's death, Slur turns to rebuilding his ranks, drawing Toramaru and Mafuyu into his organization. Sakamoto, for his part, shares Slur's true identity with Nagumo and the Order, setting the stage for the deeper infiltration to follow in the JCC Infiltration Arc.
