It's the quarterfinals of the national corporate badminton tournament. Their opponents are the powerful Unisics team they lost to in a practice match. The members of SunBev are eager to get revenge. Mikoto and Tatsuru take on Kirishima and Oginome in a rematch. Their match is a fierce back and forth game of offense and defense. From the stands, QA department employee Usuyama watches them play.
For both the team's sake and my own...
...من أجل الفريق ومن أجلي
Für die Mannschaft und auch für mich selbst.
Ni por el equipo, ni por mí mismo.
Ni por el equipo, ni por mí mismo.
Pour les autres,
Non posso farlo, 
sia per la squadra che per me stesso...
Pela equipe e por mim mesmo...
Ради команды, ради себя самого...
