Meanwhile, a bouquet of blue roses is delivered to Mari. Kusaka sees it and is enraged that anyone would dare send such a thing to his beloved woman and storms off with it.

With Kaixa and Delta can’t stand up to the Riotrooper v2, they run away with Mari. But then Kusaka grabs Mihara and tosses him back at Murakami, saying that he deserves it for daring to send roses to his beloved woman. Mihara screams that it’s a misunderstanding, and for Kusaka to help him, but Kusaka just sneers and a blue petal lands on his outstretched hand, turning him to ash.

Takumi arrives on the scene and runs into Murakami, now in Rose Orphnoch form as the Riotrooper V2 was badly damaged.

Back home, he asks Keitaro what happened to Mami, he’d left her with him before heading off to look for Mari and Kusaka. Keitaro points to a small human-shaped pile of ash. She was an Orphnoch too. Kusaka reveals that he killed the girl himself before she could transform into an Orphnoch much to Takumi's anger.

Meanwhile, Murakami’s head is rolling about when the Lion Orphnoch picks it up. Murakami asks him to bring him back to the Smart Brain headquarters, and to recover Delta’s belt at the same time; They’ll be using it to make the “Emperor’s Belts”. The Lion Orphnoch, seemingly a foreigner, speaking in broken Japanese, says that he’ll do so on the condition that he gets one of the belts; Murakami promises Leo the belt of the sky, the Psyga Driver.
