WARNING: If you don't want to spoil yourself anything of the past events of this story, I recommend you to read the previous part. Thanks.
> Your name is Daikoku "Daiko" Susumu, a hybrid of human and youkai who quietly spends most of his time locked in his house, located in the village of humans.
> You are somebody quite timid, especially because you're not used to dealing with people correctly if we talk about long conversations. Despite this, your sense of help if they have a problem is enormous, even more if you decide to solve it. Many of your friends respected you by your most important feature: intelligence. You're one of the smartest people in the village of humans, something that even the school teacher, someone with so much knowledge, has given you merit.
> So it was in the past before your radical change. You have locked yourself in your own home. You no longer have friends. No longer help people. Nobody's looking for you and you do not want them to. Hell, even you stopped attending classes. Reasons? When you begin to increase your intelligence, likewise you started to gradually see things in a slightly more mature way than others. This led you to see things from your day to day as a nuisance. Gradually you were becoming what you are now: a hikikomori.
> However, it looks like there will be a change again. One day, you were charged with requests by your beloved grandmother, being of the few days that you go out. This provoked the reunion between you and Arukas Hantai, your best friend in the past. She, without losing a trace of her usual energy or losing hope in your friendship, she accompanied you for the different things that were requested. Many things happened in the course of that day, like your encounter with the "new and improved Kuchisake-onna", your future training for danmaku, or your possible ability to predict future events, just like your missing mother.
> The most amazing event, however, is that you discovered you have a female self, locked up in your mind! After hard moments trying to free her from the box in which she was locked, you finally succeded. With her free, you can now change from a boy to a girl, and vice versa. You can even change to a cat, too! She named this ability "Soul Swap".
> She was not sure which name to take for herself, so you called her Kiku.
> You are currently sleeping after a long night of experiments.
> You can hear the birds singing. Looks like it's tomorrow already.
