>>64363693Maisondes is music group/project. The concept is "an apartment building with each song assigned a room number and being written to express the emotions and loneliness of a resident living in a one-room apartment in the city."
Hence Suisei's weird "apartment" tweet.
MAISONdes is most recently known for Tokyo Shandy Rendezvous with Kaf. They're also behind a song for the trailer OP posted, which Suisei is featured in.
