#izutade

two people will go through similar things & learn to cope in different ways

Of all the directions to take a potential spinoff, I can't think of a prompt with more potential than "Izutsumi and Inutade go on a road-trip adventure".

As a duo, the two characters are perfect foils with an excellent dynamic that's just begging to be built upon. Likewise both characters individually have plenty of room for further growth. This parallels Dunmeshi's world as a whole, which is basically nothing BUT untapped potential. What better way to explore it further than through a pair of young warriors who know nothing of the lands and peoples beyond their home?

Narratively, it would be extremely easy to set up. Inutade is sent to retrieve the escaped "Asebi," but Izutsumi refuses to return until she's killed the wizard that originally turned her into a beast-man. Izutsumi (falsely) promises that she'll return and never attempt to escape again, IF Inutade helps her with this first.

Thus begins the adventure of the cat and the giant! Two foster-sisters, seeing strange sights, getting into hijinks, and bonding as fellow oddities within this world where their kind is rare.
