Ayaka Oishi Perfect G 53 Hot May 2026

I should also check if there are any events or releases in 2023 related to her and the number 53. Perhaps a 53rd anniversary of a group, a tour name, or a special event. If not, I can highlight her 53rd work anniversary but wait, she's 23 (born in 1999), so maybe it's a different context. Maybe the song or a project is numbered G53. NGT48 uses group letters like G, S, Z, so maybe G is a subgroup.
