The Warcry of Excessiveness

To prevent the school from disbanding the rugby team, Sousuke and Kaname help train them for an exhibition match against a rival school. Upon discovering that the players are timid and passive, Sousuke subjects them to grueling basic training to toughen them up, which helps them win the match. The scene of Sousuke's grueling training of the rugby players by berating and abusing them to desensitize them to make them stronger references the boot camp scenes from Full Metal Jacket.
