Previously on black rock shooter:

after mato's transformation as black rock shooter' something was not right as she suspect her two friend's are missing and why there was unknown enemies that just attacked her school and that answer is up to mato to find out.

after the attack, mato yuu and all the other students, we're told to go home after the incident. and later the news announce, that all school's & comapny's will be forced on lock down, due to what happpend on junior high. just to make sure everyone is safe. then later mrs. kuroi said that was a risky move she did out there, but she is glad that she wasn't hurt, and that she made sure everyone didn't die. Mato's brother said, she did great out there, and that she was pretty badass. mato was happy to accept the praise, but now that this is happening, mato is trying to figure out what just cause that attack. and who did that & where did it came from. on mato's second thought, she's thinking yomi & kagari's silence, could have something to do with the attack just earlier. but she couldn't confirm if it's true or not. because to her, there's a small chance it could be true. considering they have been silent to them for 1 day, without even telling them what's their status on their side.

1 day earlier before the incident.

yomi & kagari, went to meet up with their friends in the park. because her friends invited the two to hangout with them. & play roller blades' so later in the game, while everyone was roller blading, kagari was trying to show everyone she's faster than them. and when she went too fast, she couldn't stop and later got hit by a truck. and kagari's legs got crumble. so they easily to rush her to the hospital. & yomi called her mom, to relay her what happened. so kagari woke up a few hours later. the doctor informed them, that kagari is now disabled, for the rest of her life. while later kagari was almost gonna break down, due to the news, but at the same time she had no choice but to accept it. as she cries, so later at night, yomi had to be the one to keep kagari company, at all times. so later that night, a strange green & yellow light, was coming from outside. and tried to enter yomi's house. and when it got in, it was heading on yomi's room. and the two glowing orbs merge with kagar,i & yomi, turning them into "Chariot" & "Dead master" as their original selves' are trapped deep, in an eternal slumber. while the orbs took over their body.

Back to the current day.

10 minute's later 10:30 pm, a glowing orange light enter yuu's house, and was heading upstairs on yuu's room, and when the orb entered her room, it jumped on top of yuu, and proceeds to merge with her, as her skin starts to turn tan, her hair turned white, and her eyes turned orange. then yuu was trying not to scream when she looked at herself in the mirror, she changed, then later, heads out, to go to mato's place.

20 Minute's later.

a woman named, "Saya Irino" was drinking a dozen round's of Tea, after her humiliation in school 1 day ago, during her first day lesson on another class. where she was being clumsy, and suddenly got Embarrassed by the students, after they see under saya's skirt, everyone started laughing at her, she couldn't stand the students doing this to her, she grabbed her bag and leave the classroom. all the other teachers we're asking her where is she going, but saya was so broken, that she couldn't turn around, as she cries and walk's away. their principal tried to reach out on her, but he couldn't, and felt terrible, so they scold the students about what they did, so the student's felt sorry, for what they did. saya felt traumatize, & doesn't wanna go back to teach again. but the more she thinks about it, the more she starts have a mental breakdown. so she breaks down, grabs a knife & tries to commit suicide. but she couldn't do it, because she think's there's still someone out there, who still care's for her. so she put down the knife, and went to the kitchen' to grab another round of Tea, but while she was making Tea, a red glowing orb jumped into to her cup, while she was facing the other way. she didn't bother to notice, due to her mind couldn't even think properly. so when she drank the Tea, with the glowing orb in it, she began vomiting, and started feeling like her whole throat is like on fire. then later her hands start shedding, and grew monster hands, & she grew horns on her head, as her skin starts to turn pale, and her eyes turning red, she make an evil Laugh, & said "i... am Black Gold Saw!"' and once her transformation was complete, she head's out in the night, and tries to meet up with Chario,t & dead master.

10 minutes later, after black gold saw's Transformation.

after Black gold Saw's transformation, Yuu was heading to mato's house, but she heard a mysterious laugh from the distance.
and instead, she decided to head where it was coming from. but she realize that without mato, she would be at risk. so she continues to head to mato house. later mato heard the same noise too, so transforms into her costume & proceed to head out, suddenly, yuu and mato saw each other on the roof top's, and mato was shock, to see what has Yuu become. so yuu explained what happened, and mato asked what is she doing outside in the middle of the night, so yuu said she heard a strange laugh coming from the distance, mato said she was out for the same thing, so the two teamed up, to find out where its coming from, and to go to yomi's house to see if she's home.
