CGC x JSA Announce Exclusive Public Signing with MAH at NYCC

CGC and JSA are thrilled to announce that singer MAH, lead vocalist of the Japanese punk/metal band SiM, will be joining us for an exclusive public signing at New York Comic Con alongside Robert McCollum and Lydia Mackay!

SiM is a Japanese alternative metal band formed in 2004 in Shōnan, Kanagawa. MAH has been the vocalist for SiM since its formation in 2004 and also played guitar for the band prior to SHOW-HATE joining. He started the band alongside KAH and WAY.

Known for their dynamic fusion of hardcore, punk, metal, reggae and ska, SiM has built an international following. The band rose to worldwide recognition with their hit “The Rumbling,” featured as the opening theme for Attack on Titan: The Final Season Part 2.

MAH will be signing on October 10, 2025, from 1 p.m. to 2:30 p.m. at the CGC Signature Series x JSA Booth HB-906 (pre-order tickets here). All submissions must be dropped off at the booth during these times. This signing is sponsored by FGS Autographs.

The signing fee is $100 per signature and includes JSA witnessing. If you need a collectible to have signed at the show, a limited edition vinyl record and prints will be available to purchase at the CGC x JSA booth.

IMPORTANT: Collectibles CANNOT be submitted for this signing through the mail.

If you're unable to attend NYCC but would still like to get in on this amazing opportunity, you can submit your collectibles to FGS Autographs by mail. A limited number of spots are available, so don't wait!
