"I meant to tell you sooner, but I never expected her to follow us here in person. That's why I waited until now."
"..."
Lingmeng didn't look like she was lying. Kotori fell silent for a moment, then immediately picked up her phone.
"Hold on. I'll ask Reine to send over the footage so we can check."
To be safe, Fraxinus had sent a miniature surveillance camera to follow Kurumi after she parted ways with Shido and the others.
If Lingmeng was telling the truth, the camera should have caught it.
"Reine... Yeah, it's me... Could you send me the footage from the camera following Kurumi? I want to take a look... Okay, thanks..."
After a brief call with Reine, Kotori took out a terminal and set it on the table.
A notification sounded from the terminal. Reine's video had arrived.
Gulp.
Kotori swallowed and opened the video.
On the screen, Kurumi stood amid a vast pool of blood in a dim alley.
Then AST arrived, and Mana, clad in a Realizer, swiftly cut off Kurumi's head.
The whole sequence lasted only a few minutes, but what it revealed was far more than the footage alone could explain.
"What's going on...? Why would Mana...?" Shido asked shakily as he watched her on the screen.
"Don't ask me. Who am I supposed to ask? Anyway, your biological sister is quite the mystery.
She managed to join AST, and she can even kill Spirits.
I'm getting more and more interested in who you really are, Shido."
Lingmeng spoke with keen interest as she watched Shido frown in distress.
By the next morning, Shido, Lingmeng, and Tohka had arrived at school.
"..."
Shido stared silently at Kurumi's seat, his face clouded with gloom.
Kurumi Tokisaki was dead. They had learned that yesterday.
