Born from a member’s doodle and quietly making appearances on social media, the ASTERISM MONSTER—aka “Asumon”—has now been transformed into a full-blown metal T-shirt!

Introducing: the “Asumon ASTERISM MONSTER T-Shirt 2025”!
Will there be a 2026 version and beyond? That depends on the response—no pressure!
Stay tuned for more from Asumon!

The first release will be at “J-POP SOUND CAPSULE in LA” on Monday, July 2 (PST)!
After that, the T-shirt will be available exclusively at live venues (for now).
※Online sales will be announced on our official website and social media once confirmed.

Check below for product images and pricing!
