Mushoku Tensei Cosplay: Minato Mira’s Roxy Migurdia Charms with Shy Poses at Ultra acosta!2026

Cosplay fans at Ultra acosta!2026 were treated to a spot-on take on one of Mushoku Tensei’s most beloved heroines. Cosplayer Minato Mira (X: @tehslu_cosab_xx) appeared as Roxy Migurdia, pairing a shy, fidgeting pose with braided twintails recreated in loving detail.

Ultra acosta!2026 Welcomes 24,000 Visitors in Ikebukuro

The cosplay event ran from September 4 to 6, 2026 at Sunshine City in Ikebukuro, Tokyo. Held as a super-expanded version of the long-running “acosta!” event, Ultra acosta!2026 drew a total of 24,000 participants across its three days.

On September 4, an all-night program gave attendees access to the Sunshine Aquarium after closing hours, with the facility rented out as a venue for photography that would normally be impossible to attempt.

At the Sunshine City Fountain Plaza, the stage program included CDEF, in which participating teams showed off dance performances in cosplay. September 5 also brought the cosplay doujin sales event and flea market acosta! Marche at the same time. September 6 was rainy from morning to night, but across all three days the event attracted a large number of cosplayers and photographers.
