But she knows what happened after sex, too! She didn’t like that.
This episode was rather… plain. Okarin’s quest is to undo all the D-Mails sent to the past to regain access to the IBN5100. First target: Feyris (Rumiho). Rumiho somehow remembers what happened before she sent the D-Mail and the contents of it when Okarin gives pieces of information about it to her. But since she revived her dad with the D-Mail, she is reluctant about telling him.
That people other than Okarin can regain their memories from before the world line move makes things a lot easier. He can ask for the cooperation of the involved parties to help achieve his goal: undoing all D-Mails. But this means that eventually, Urushibara Ruka, our delicious cake, will be armed again and return to being a delicious trap. OBJECTION!
When Rumiho gets all dere in front of Okarin, I seriously thought he is going to cheat on Kurisu, but I’m glad he didn’t. Kurisu is our one and only strict tsundere tensai hentai 2ch shojou.
