Miho is determined to bridge the gap of animosity between her best friend Emi and her sister Maho, and arranges a Tankery practice match between the two teams. After the match, Emi gains admiration for Maho as a person, but is perplexed by Maho's absolute ruthlessness on the field. This new revelation also shocks Miho to the core, as she tries to accept that her sister's - and her family's - Tankery style run contrary to her own values. Family ties and precious friendships will be tested as Miho ponders whether she is even cut out for Tankery to begin with.
