Re:Creators: One More!

The story is about Miharu, a teenage otaku girl who has a crush on Shou (MC from Yuya Mirokuji's manga). One night after going to get a figurine of Selesia, she encounters the real Selesia and Meteora fighting Altair in the Park. A few days after that, she is out shopping with her friend Shiori at Sunshine, when she witnesses the fight between Selesia and Mamika and the appearance of Yuya.
