The two students had gone on two different sides, making sure to act normal while the Vampires pass by. Then from behind, they could use stealth mode to capture them.
From where Kevin stood, he spotted the vampire coming, so he acted like he was listening to what was being said at the front while the vampire passed by him.
Just as the Vampire walked past him, Kevin activated his shadow Eater on the vampire and he was drawn into the shadow realm by the shadow hands emerging from the ground.
The light and dark students who saw this shrieked out with fear. The assembly was dissipated and each was wondering what was happening.
"V3, V5 do you copy, what's happening?" V1 said.
"Leader, I can't reach V3, I think something happened to him like V4," V5 said.
