Wataru is the leader of the head of the Humanity Recycling Research Society. He disassembles home appliances, and repairs them upon request. Explosions are an unavoidable part of his research, and he often causes trouble by getting those around him involved. 

A cat-like alien from a distant galaxy, MuMu, arrives on Earth. His goal is to learn about home appliance technology on Earth to recover the technology his species has lost. The protagonist, Sakurako, has a typical university life, but everything changes with MuMu's arrival! What begins as an unexpected cohabitation quickly turns into a whirlwind of chaotic events. The chemistry between Sakurako and MuMu leads to a super-spectacular, appliance-filled, and cat comedy adventure.
