In this episode, everyone is recovering from the previous episode with the black widow yokai, and Zakuro tries to find out about what happened to her mother. Meanwhile, Ganryu is upset that he had not been able to do anything during the battle and we learn more about Bonbori and Hozuki’s past.
The opening is Agemaki turning in the report on the case to Hanadate, who apologizes for his less than stellar performance (since he was captured by the spider yokai). Hanadate asks after Zakuro, and Agemaki says that she is fine. Then Hanadate gives Agemaki a bag of cookies intended for Zakuro and the team. (At least it wasn’t candles.)
The scene after the credits is Kushimatsu and Lord Amaryoju discussing what happened during the previous episode, specifically the yokai mentioning the name of Zakuro’s mother. Kushimatsu mentions that Zakuro has been upset since the incident, and Lord Amaryoju notes that she also appears to be upset. He then counsels patience, stating that Kushimatsu needs to stay strong in order to take care of the girls.
Meanwhile, Agemaki arrives with the cookies. There is a little exchange where Agemaki is exasperated by how Zakuro goes from gloom to absolute delight when she finds that the cookies are from Hanadate. Then she turns sad again, and when Agemaki notices, she glares at him. This extends into a little scene where everyone is trying the cookies. (Since they’re referred to as “bisukketo” I’m pretty sure they’re intended to be English tea biscuits.) Everyone is enthusiastic about trying them, even Zakuro. Agemaki thinks that he should not tell her milk is involved in the recipe.
The twins meanwhile are having trouble with their partner, Ganryu. He is upset he wasn’t able to do anything during the previous episode’s battle, and wants to be left alone. When the twins are persistent, he yells at them, then apologizes. (He is apparently aware that he is being a little bit of a jerk over the entire “wasn’t able to fight, had to be protected by girls” thing. On the other hand, he is basing his upset on being “inexperienced” not on the girls themselves, so he gets back all the “good guy” points he lost by being a jerk in the first place.)
Bonbori and Hozuki try to reassure him that he was not being inexperienced or incompetent by telling him that they like him and wanted to protect him. This results in a conversation where Ganryu wants to know how they could risk themselves over someone they had only met and started working with recently. They say they love him, and he is extremely upset, because the situation was dangerous, and they could have died.
They explain why, by telling him about their child hood. They had been kept hidden in a cave from the time they were very small children. Somehow, their presence had been discovered, and their mother had been killed because she had hidden them. They were driven from the cave by their mother’s husband, and were rescued by Kushimatsu. The explanation behind the story is that they did not want to lose anyone they cared about, the way they had lost the one who had been caring for them. They also talk about their past when they were first living with Susukihotaru and Zakuro, and at one point cheerfully talk about how they had not even known how to speak out loud. (The last is the straw that breaks the camel’s back for poor Ganryu. He’s very upset for their sakes, because of how horrible their lives had been until they’d been rescued.)
The next scene is a long flash back about all the girls when they were little. It focuses on Bonbori and Hozuki, then moves on to their relationship with Zakuro. We also see some of Susukihotaru’s memories about Zakuro, which eventually resolves to the present. Through other flashbacks, we learn a little more about the relationships the girls have with each other and to Zakuro, and about the mystery surrounding Zakuro’s mother.
In the next episode, Agemaki is extremely reluctant to visit his folks.
