【PC+KRKR+安卓直装】恋し彩る正義爛漫

――子供の頃、正義のヒーローになりたかった。

みんなの平和を守り、悪を成敗する。

鋼錬寺颯斗は、そんな強くて勇ましいヒーローにずっと憧れを抱いていた。

けれども所詮、それは子供の戯言で……

いつしかそんな夢は、年を取るとともに消えていった――

時は流れ。

新しい学園へ進学するにあたり、田舎から親戚が下宿を営む都会へと引っ越してきた颯斗。

田舎とはまるで異なる賑やかで明るい都会の光景に戸惑いながら町並みを歩いていた最中――

いかにも怪しげな覆面集団が引き起こしたバスジャック現場に遭遇してしまう。

足が震えて逃げられもしない颯斗。

そこに、純白のスーツを身にまとった１人のヒロインが颯爽と駆けつけてきた。

「この世に蔓延る黒い闇を、白い光で斬り払う！

正義の使者『マロンブランシェ』、ここに見参ッ！」

華麗な舞で覆面集団を蹴散らす変身ヒロイン――

思わず見とれていた颯斗は、彼女たちの抗争の渦中に巻き込まれてしまう。

その時、図らずも見てしまった彼女の正体は、なんと幼い頃からよく知る従妹の白河美栗だった。

「誰にでも人には内緒にしておきたいことってあると思う。

だから、このことも誰にも内緒にしておいてほしいな」

美栗とそんな約束を交わす颯斗。

正義のヒロインに、悪の組織、そして知ってしまった従妹の秘密……

颯斗の新しい学園生活は、そして下宿での生活は、いったいどうなってしまうのか――

――When he was a child, he wanted to be a Hero of Justice. To protect everyone's peace and defeat the evil. Kourenji Hayato had always admired such strong and gallant heroes. But after all, it was just a child's daydream...... Before he knew it, as he grew older, that kind of dream had faded away――

Time passes, at the time to enroll at a high school, Hayato moves from the countryside to the city where his relatives run a boarding house. A bustling and brightly sight that is quite different from the countryside, while he is walking in the street in bewilderment―― He runs into a bus being hijacked by a very suspicious​ group wearing masks.

Hayato is trembling and unable to escape. Then, dressed in a pure white outfit, a heroine comes rushing in gallantly.

"The darkness that is spreading in this world, shall be slashed away with white light!

The Emissary of Justice "Marron Branche", here I come!"

The disguised heroine disperses the masked group with her spectacular moves―― Unconsciously captivated by the scene, Hayato gets caught up in the midst of her fight. At this time, he accidentally sees the identity of the girl, and to his surprise, she is his cousin whom he has known since he was young, Shirakawa Mikuri.

"Everyone has things they wish to keep as a secret for themselves.

So, I wish for this to stay as a secret from everyone."

Hayato makes such an agreement with Mikuri.

The Heroine of Justice, the evil organization, and finding out the secret of his cousin...... Hayato's life at his new school and the boarding house, what is to become of him――
