A Milestone Gathering at Sofmap AKIBA
The 30th iteration of the Kosumap photography series gathered a diverse roster of talent on October 15. Alongside returning figures Teera Okudera, Nano Kawai, and Miuchan (Koha Chiba), the lineup introduced three fresh faces to the Akihabara stage: uNa, sister, and Kanade Hamano. The event utilized black cat-themed attire courtesy of the dress brand vanityME.
Streamers and Campus Talents Step Into the Spotlight
The newcomers brought distinctly different backgrounds to the stage. uNa and sister, who frequently collaborate on broadcasts, are streamers on Niconico and Kick. uNa, who spent her early childhood in London until age five, noted a desire to lean further into cosplay and voice-based projects. Meanwhile, sister combines casual chatting and core gaming broadcasts—highlighting recent clears of titles like Nioh 3—with digital design work utilizing Adobe software to create original art and merchandise.
Hamano emphasized her stamina and packed daily schedules, pointing to IVE member Rei as her stylistic inspiration alongside her distinct left-eye tear mole.

The two-day event, running on October 31 and November 1, will feature live broadcasts spanning from 13:00 to 17:00 on both days, bringing their digital chat dynamic directly to one of Tokyo’s physical cosplay celebrations.
