A kappa, living in the kappa town under the mountain behind the waterfall, as a kappa engineer, with my own kappa laboratory. I'd share plans with Nitori, build tanks and random stuff with Rika whenever she drops by, go down to the village every now and then to sell my inventions to villagers or Kourindou, get hired to fix consoles, computers, etc. at Eientei for the resident NEET, Kaguya, probably argue over electricity rates with the Tengu upstairs, and essentially binge on cucumbers.
