Senpai Was Amazing.

Tetsurous attraktive Schwester Manami nimmt Kaito heftig in Beschlag und heizt damit die Verwirrung der Gefühle und Phantasien noch weiter an.

Things turn awkward the next day, but they try to put it behind them. More complications arrive when Manami, Tetsurō's married sister, takes a homebound Kaito for shopping. Ichika sees them, and followed them via teleportation with Rinon's help, even at her place. Worried about what will happen next, Ichika enters and tries to take him home...though not without clashing a bit with Manami, acting like an overprotective lover, until Tetsurō comes to clear things up, that Manami is already married, and she's here because of a petty quarrel with her husband. As an apology Ichika asked Kaito for a favor from him. He asked if she could help him review for the finals, to which she agreed, and helped him study until the final day of exams.

関係が微妙にギクシャクし始めたイチカと海人。 頑張ってお弁当を作ってみたり、普段より早く登校してみたり、 いつもと違う様子の二人を不思議に感じる檸檬や哲朗。 そんなある日、海人は哲朗の姉・真奈美の買い物に無理矢理付き合わされる事になる。 偶然２人を見かけたイチカはその親しげな様子に憤慨するのだが…。

Las cosas se ponen raras al día siguiente, pero intentan dejarlo atrás. Más complicaciones llegan cuando Manami, la hermana casada de Tetsuro, lleva a Kaito de compras. Ichika los ve y los sigue vía teletransportación con la ayuda de Rinon, incluso al apartamento de Manami.
