Episode 1 - Touka:
With Touka and Chika joining the Saiga family, our protagonist's home life has changed a great deal. Despite initial concerns about how things will go, Touka demonstrates her all-encompassing flexibility and becomes a happy member of the family.
One day, our protagonist notices Touka looking out of sorts. He grows worried that she may be tired or overworked. After much deliberation, he comes up with a plan to address this concern: giving Touka a well-deserved surprise party.
 
Episode 2 - Makibishi Nanako;
After several tumultuous days ensuing from the death of their grandpa, peace has finally returned to the Saiga household. Having overcome her grief, Nanako is now fully devoted to following in her beloved grandpa's footsteps and becoming a master inventor.
Our caring protagonist, however, worries she may be working herself too hard. Just when he resolves to give her a chance of pace, the neighborhood kids are horrified by a ghostly appearance. With the friendly local tanuki Shinobi determined to protect the city's peace, the Shinobi ghost busters ride to the rescue!
Under this eerie onslaught, what fate awaits Nanako and our protagonist?
 
Episode 3 - Nekoe Chika:
After the dust from the Saiga succession war clears, Chika ends up freeloading in the protagonist's home. Naturally, instead of seeking to fit in and live happily with everyone, she keeps playing pranks on everyone (okay, mainly Nanako).
This culminates in Chika breaking a beloved heirloom vase, at which Nanako flies into a rage. Though this was a genuine accident, the result is nevertheless Chika's fault for being negligent.
She acknowledges her guilt, but, unable to offer a sincere apology, she instead runs away from home. Will she find her place in the family, or is this the end of their short time together?
