Yoshiko didn't think anything special of Riko 3 years ago. Back when Yoshiko asked Riko out to her house and set up candles in a dark room. At first, Riko felt... insecure. The dimly lit room having only candles and the weird glowing star like mat as a light source, creeped Riko out a bit. However, she could see Yoshiko was enjoying everything about this, Yoshiko just wanted someone to accompany her in her "devilish deeds".
And this made Riko garner a special feeling for Yoshiko. Yoshiko on the other hand, had no feelings for Riko. Sure, Riko was always being with her, being her "little demon" but for her it was normal. Sometimes she asks herself if she was eccentric or if the world is just that boring.
"Yoshiko-chan?" asked Riko while looking at the grimoire Yoshiko was holding.
"What is it, my little demon Riri?"
"Can I join the ritual this time instead of just watching?"
Yoshiko's eyes lighted up.
"Of course!" Yoshiko shouted.
Aware that she broke out of her Yohane character, she cleared her throat. That day was one of Yoshiko's and Riko's happiest days. The room was filled with laughter.
