<Comment by Rikuya Yasuda>

I’m Rikuya Yasuda, who will be in charge of the voice of Sakuya Otsuki.
Even if you are killed, you will be revived and unravel it. I will do my best to convey the foul-like ability and the charm of Sakuya, who confronts unrefined incidents while embracing the suffering. Don’t miss their performance until the end! !

<Comments from Shion Wakayama>

Lirithea, whom I play, is a kind, pretty, cute, condensed child who likes the world. She looks so clear, she’s shy and blushes, she’s talking like a buddy, but she suddenly makes cold retorts… I’m going to love Liritea-chan, who has all kinds of aspects!
