Aboard the Space Battleship Tiramasu during a civil war between Earth and its space colonies, the Ace pilot Subaru Ichinose tires to eat his fried pork skewers without being criticised.

Subaru Ichinose picks up a stray Space Chihuahua and tries to secretly keep it as a pet in his cabin. However, Subaru is forced to make a difficult decision after the dog starts to rapidly evolve.

Ligier Leroy, a new pilot on the Tiramisu, gains the attention of the men aboard the ship and forces Subaru to have to fight in her personal mech suit full of stuffed animals and lace.

Subaru struggles in an intense battle after he starts to feel the consequences for he drinks too many cold drinks and can't find a bathroom to relieve himself whilst still making sure to win the fight.

Despite Subaru's love for plain white rice, Subaru finds himself stranded in space, surrounded by white rice and desperate for different food to add to his rice bowl meals before he starves.

The crew of the Tiramusi join for a morale-boosting session with the captain. Subaru is excited to experience some seasonal festivity that he had missed out on during his childhood.
