[Kurodou Holdings "Kabu" (Kurodou Katana)] Boku wa Oketsu Gakari {Chin²}

On a table tennis club table, a third-year club member in a track jacket finds his senpai status worthless the moment his underclassmen pin him down and inform him he's the club's designated 'butt duty' officer. What begins as one boy's panicked protest ('Not inside! You'll wreck my stomach!!') spirals into a rotation where second-years and even first-years take their turns, with the pink-haired victim reduced to begging while his juniors lecture him that 'this is a meritocracy — the strong give orders, and the weak listen.' Between rounds he's subjected to household equipment maintenance spray used as improvised 'punishment' under the jeering banner of the 'hammer of justice,' and his desperate final gambit — challenging his tormentors to an actual match to win his freedom — is swallowed by the cruel logic of the pecking order. The artwork emphasizes his slender, sweat-slick frame and flushed, tearful face against the flattened bodies pressing him down, keeping the focus on the gap between his seniority and his total helplessness. A bleakly comedic, merciless power-fantasy reversal where the club hierarchy inverts completely and the once-proud third-year discovers exactly what 'weak' means in his new club's constitution.
