Tayutama: Kiss on My Deity EP6 - Happily Married Couple

Yuri's sister ends up with Ho stuck on her head (the phoenix is formed when Ho and Oh are combined) and Mashiro plans to bring Ho onto her side by helping him regain power and show him their kindness. This is possible only when Yuri's sister is happy and to do this, Yuri has to stay by her side all the time and he disguised himself as a girl to do so and constantly changes form to attend classes. They then have an outdoor class where they remember their past about how they both used to play with Ameri all the time after which they are attacked by crows. Even though he gets injured in doing so, Yuri attempts to save his sister who is moved by this and she begs Ho to save him. Ho then transforms into a bird and all the crows bow down to him and finally leave. Yuri finally realizes that the other controller of the birds was Oh.
