Suppose you were just pretending to be lovers, but somehow the pretense transforms into the real deal!

Tatoeba Engi de mo Koibito no Furi o Shite Itara Honki ni Natchau Koto mo Arimasu wa yo ne! Na Jōkyō (たとえば演技でも恋人のふりをしていたら本気になっちゃうこともありますわよねっ！な状況)

Shōma arrives with a delivery of firebombs. Kikyou is determined to expel Lloyd's treant and convinces him to have an antidote massage, but is forced to flee when Selen sees her trying to stick the antidote down Lloyd's pants. Lloyd goes to a hot spring, not realizing it is mixed bathing, and Selen is furious when her lewd plans are interrupted by the arrival of Riho, Marie, Alka, Phyllo and Mena. Kikyou meets Minoki, Threonine's secretary, who reveals he is responsible for the treants. The Demon Lord of Trees, Erkling, takes over Minoki. Lloyd easily deals with the treants while Erkling heads for the hotel. Selen's father reveals he has been legally dealing in treants with Shōma. 

Lloyd's friends hold Erkling back with the firebombs while Lloyd tears out Erkling's demon seed, returning Minoki to normal. Alka is later confronted by Shōma, who leaves after revealing he has been working with one of her enemies since the holy sword was removed. Selen's father cancels her arranged marriage and lets her continue her career as a soldier. Alka tries to con Lloyd into giving her a massage for her hard work, but Lloyd inadvertently performs a German Suplex instead.
