Toujima Tanzaburou wa Kamen Rider ni Naritai

東島丹三郎は仮面ライダーになりたい

Tanzaburo Tojima has dreamt of becoming a Kamen Rider his whole life. But now that he’s 40 years old, he’s starting to think his dream may never come true…until he’s swept up in a series of crimes inspired by the infamous “Shocker”! From Air Master and 81 Diver’s Shibata Yokusaru comes a wild, heartfelt tale about adults who love Kamen Rider a little too much and start playing pretend—for real! (Source: Crunchyroll)
