Even a little girl can transform! Tsurumi Rumi (鶴見 留美), an elementary school girl who Hikigaya Hachiman (比企谷 八幡) and co. save her from bullying by her clique during Summer camp at Chiba village. However, they don’t expect she transforms in front of them! For some people, it is changing. For me, it is the change, “The Transformation”.
Actually, this is Oregairu analysis focused on a certain girl, but I included how a certain character will transform too. For how Yukino will transform and the reasons why she will change, I wrote in after Rumi’s phrase. So you can find it so easily by Ctrl+F and keyword [New].
