The official YouTube channel for Arika, a unit consisting of voice actor and singer Yuko Natsuyoshi and guitarist and composer Yamato, has started streaming a special music video for “inclusion,” the ending theme song for the TV anime Unnamed Memory season 2.
The unit previously provided the anime’s first season ending theme song “blan_.” Natsuyoshi, who has voiced Sylvia, one of the main characters in the anime since its first season, also wrote the lyric of “inclusion.”
The clip is composed of footage from the anime story. Natsuyoshi wrote on her official X (formerly Twitter), “And…, Oh my goodness… An anime music video has arrived, what should I do… My dream of becoming a voice actor and having an anime music video for a song I wrote the lyrics and sang has come true… Oyoyo…”
