The only human girl (self-proclaimed succubus) Sakura from the Monster Girl Class embarks on a cross-species yuri school life! Participating in a hands-on learning experience at a nature-rich coastal branch school, Sakura encounters a mysterious slime girl, Komari, at the beach, who shows her the ability to transform into others and asks her to be a model. Later, Sakura goes to fetch the serious Skura girl, Narumisaka Mai, who has a strict attitude due to her prejudice against succubi, and due to an unavoidable accident, she ends up pressing her ample chest against Mai through her swimsuit. Interpreting this as a declaration of war from the succubus, Mai retaliates by entangling Sakura's soft body with her slippery tentacles, igniting a battle that cannot be lost between the self-proclaimed succubus and the Skura girl, where pride and flesh intertwine――. The fifth volume also features a centaur wielding a naginata in a horse girl martial arts tournament and a lamia cellist utilizing her snake body, giving a glimpse into how demi-humans engage with human society! Don't miss the intermission four-panel comics and the newly illustrated manga featuring Arachne reader models!
