Sousuke nimmt jede "Mission" ernst. So spielt er auch den Freund von Mizuki. Während Mizuki und ihre Freundinnen Sousuke näher kennenlernen, zeigt sich bei Kaname die erste Eifersucht. Dabei setzt sie auch gerne mal ihre Lieblingswaffe, einen Papier-Fächer ein. Ich glaub der kann ganz schön weh tun, wenn man sich Sousuke so betrachtet.
Putting the tumultuous experiences in Khanka behind them, it’s business as usual back at Jindai High School. On the way to school, Kaname is asked out by Shirai, even offering to leave his girlfriend, who watches the debacle furiously from cover. After Sousuke threatens to kill off his family if he goes near Kaname again, the situation appears to be resolved-or is it? At school, Kaname gets the strange feeling that she’s being watched. The situation explodes when Sousuke finds foul graffiti written about Kaname scribbled on the men’s room wall, and proceeds to torture and interrogate Shirai trying to get him to confess. Kaname is called in by Kyouko to defuse the crisis before Shinji’s bladder bursts.
Once Shirai is rescued from getting intimate with the toilet bowl by his enraged girlfriend Mizuki, Sousuke sets out to learn about love from one of Shinji’s dating simulators. Kaname and Kyouko watch with distain as negotiations break down between Sousuke and his virtual love. While Sousuke hasn’t got a clue about romancing virtual girls, this military maniac is about to find himself on the receiving end of a crash course in the real thing courtesy of Mizuki Inaba. Blaming Kaname for Shirai breaking up with her, Mizuki recruits Sousuke to fill the roll as her beloved boyfriend in the hopes of convincing some old friends from Jr. High that she has the perfect relationship. Will Sousuke survive basic training in the art of romance? And just how much of this insanity is Kaname going to stand for?
