Welcome Back, Alice

The course of this manga also involves honest ramblings in form of journals of the author, Oshimi's, experiences himself from his younger adolescence to early-adulthood times. The two main characters are Kei Murota and Yohei Kamekawa, whom Kei is close friends with since childhood and calls for strange encounters of intimacy revolving around their gender identity.

Welcome Back, Alice is about a group of three friends, Yohei, Kei, and Yui, who are reunited in high school after Kei moves back to their town. What could have been a straightforward love triangle becomes complicated and dramatic when Kei shows up looking and deliberately dressing like a woman, with female school attire as well as long grown luscious hair. This predicament brings conflict and disagreements between the three as Yui has always had romantic feelings towards Kei, as Yohei is with Yui.

Yohei Kamekawa (亀川 洋平, Kamekawa Yōhei) A high school boy and the main character. Nicknamed "Yo". Yui Mitani (三谷 結衣, Mitani Yui) A girl who Yohei had a crush on as a child. Kei Murota (室田 慧, Murota Kei) The childhood friend of Yohei and Yui who comes back looking like a girl. Kei is very sexually blunt and forward. Kei says that they are no longer a boy, but does not state that they are or wish to be a woman.

Oshimi has stated that Welcome Back, Alice is about deconstructing male sexuality, with the author drawing from personal discomfort with manhood. The manga deals with adolescent sexual awakening, love and frustration among all three main characters, and the gender identity of the character Kei, as well as Yohei later in the story. Oshimi claims to have felt the need to begin an introspective journey through "the hell of sexuality" after reading Masahiro Morioka's Confessions of a Frigid Man, and that led to Welcome Back, Alice being conceived.
