This commemorative work for Ono Rikka's 5th debut anniversary is truly spectacular. Featuring 31 cosplays, from sailor uniforms to fighting game costumes, bunny swimsuits, and cheongsam, it offers daily variety and immense enjoyment. When I watched it, the fighting game cosplay highlighted her natural cuteness, while the idol cosplay was so authentic it captivated me. With over 4 hours of runtime, Rikka's charm explodes throughout, never boring. The rare saliva-drinking scene showcased a seductive side, raising hopes for future works. Her growth over five years, evident in deep throat and versatile acting, is awe-inspiring even for non-fans. I eagerly anticipate her continued evolution. Choosing a favorite cos is tough, but I definitely hope for a sequel.
