Basically this story is official Prologue for the Movie Paradise lost
Takumi and Keitarou are having a stroll when they find a girl crying in a playground. Her name is Mami, and she says her mother turned into a monster and attacked her.
Takumi brings her home and finds that her mother, and all the people in the block, are Orphenochs. He escapes with her.
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 mother-wife-figure-lover-thing and storms off with it.
Keitaro gets a phone call from Mihara, warning about the blue roses; Anyone who touches them either turns to ash or into Orphenochs. All the other Ryuusei-juku members turned to ash except for him and Kimura Saya, who turned into an Orphenoch.
A bunch of Riotroopers show up and start attacking people. Kusaka defeats them on his own.
Mihara/Delta meets up with Kusaka and Mari, and one more Riotrooper shows up. It seems to be different from the others (Riotrooper ver. 2), and is equipped with the Faiz Blaster. Kaixa and Delta fight it and its helmet is damaged and reveals that inside is the Rose Orphenoch. Kusaka thinking that it was Mihara who sent Mari the roses.
Anyway. Kaixa and Delta can’t stand up to the Riotrooper v2 and 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 you know the rest.
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 Orphenoch form as the Riotrooper v2 was damaged too bad.
Murakami uses Delta’s mission memory to power up a Faiz Edge he had and they fight a bit. Mari then shows up and tosses Takumi the Faiz Blaster. Murakami curses her; He was hanging around the area because he was looking for it.
and the story continue in the movie paradise lostTakumi transforms into Faiz Blaster, cuts off Murakami’s head, and goes home.
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 Orphenoch too. Kusaka did it.
Meanwhile, Murakami’s head is rolling about when an Orphenoch (the Lion Orphenoch) 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 Orphenoch, 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.
