“I have been given the chance to sing the opening song of The Morose Mononokean! I read the manga before coming to sing the song. But I’m looking forward to it even more because Yūki Kaji, a voice actor I like, is playing the part of the protagonist Hanae Ashiya! Please be sure to listen to ‘Long Time Traveller’!
