[Crossover] Shiina's Life at Rikkai Dai

Shiina Ren has seriously wondered why he joined a demonic tennis club just to put himself through this (not really).

Time Government: Can't be helped, Shiina. We're all wage slaves here, so let's be understanding!

Swords: Our master is exhausted again today.

Tennis Club: Hang in there, Shiina!

In short, this is a story about Rikkai Dai achieving a third consecutive championship.

Theme: From someone who wants to record a little bit of youth.
