I imagine dlc might introduce one or two comedy or lighthearted routes depending how many they´re able to make, so here´s my idea

>Sirei catches Darumi playing games and eroges on the computer in the war room and is furious
>announces in front of the entire SDU he will harshly punish her
>Hiruko comes forward and pleads with Sirei if she may be allowed to come up with the punishment carry it out herself on Darumi
>Her punishment is walking Darumi around on a leash and enacting public puppy roleplay with her
>fuck it, throw in Shouma using is pet caring skills as well
>Hiruko also trains Darumi on her battle and hunting skills, injects more animalistic techniques into them
>on day 99, V´ehxness jobs to Darumi violently clawing and ankle biting her like a dog and every one lives and boards the escape pod
