Controversy[]

In late 2022 after masa's song Onigumo to Kitsune no Shishi to started becoming popular in social media platforms like TikTok, a user uploaded an unauthorized reprint of the song to Spotify which led to masa threatening legal action and encouraging doxxing on this person. This was heavily criticized by fans since the uploader was a minor.

masa also threatens the minor on Twitter by telling them to expel from school for illegally copyrighting his songs on Spotify. Later, he was mentioned that he just threatening the person to scare them off, not actually expelling them.

The tweets have since been deleted right after.
