"Keep it open," Kagami urged Ren, as she stepped closer to the forming gate. "It will collapse the moment you lose focus."
Ren gritted his teeth and concentrated on the energy streaming from his hand and then into the air. A glyph had formed behind him, flowing new energy into Ren's arm as he kept the link open.
Kagami slipped through first with an elegant jump toward the other side. By the time Ren stepped forward as well, the tear had started to shake and collapse onto itself bit by bit. He crossed just as it sealed completely, leaving no trace behind except for a few sparks drifting into the air.
As soon as he was on the other side of it, Ren's legs started to give way from the effort. He pressed a hand against the wall beside him to steady himself, as he felt his stamina failing him.
"You burned through too much focus," Kagami said, looking down at him without any attempt at comfort whatsoever. "The spell was raw, and you let it take too much from you."
