If you are blessed with the opportunity to make a sequel, please include the following scene from book 5, chapter 4:
Chaika is house-sitting while Kio and the gang are off at the school festival's opening parade. Ichika comes over to hang out with her pal 6-chan, but he and all the other assistoroids are helping with the festival, and won't be back until late. Easy-going Ichika pulls out a bag from the local convenience store and suggests they share the contents. Which includes beer...
When the gang gets home, they find two dead-drunk loli catgirls surrounded by empty beer cans and snack wrappers, singing "That's The Way" by KC & The Sunshine Band. Blues-style.
