かつて大いなる危機より地球を守り抜いたヒーローがいた……。そして今、再びの危機に眉難高校『地球防衛部』より新たなヒーロー爆誕！ ……え？ かつてのヒーローって誰だって？ そりゃ『あいつら』ですよ『あいつら』。……え？ なんで名前をぼかすのかって？ そこはマルチなバースな設定なんでゴニョゴニョ……（うやむや） とにかく新たな防衛部――雲仙新九郎、酸ヶ湯愛琉志、卯花惣輔、長万部潮、阿蘇空太をよろしく！
Once upon a time, there was a hero who protected the Earth from a great crisis... And now, in the face of another crisis, a new hero is born from Binan High School's "Earth Defense Club"! ...Huh? Who were those former heroes? Well, it was "those guys", "those guys". ...Huh? Why are you blurring out the names? It's a multi-verse setting, so mumble mumble... (vague) Anyway, the new defense department - Unzen Shinkuro ,Sukayu Narushi, Unohana Sousuke, Oshamanbe Ushio and Aso Akuta.
