Hikaru's heart is pounding hard - having seen the wall at about the same time as Kaoru. His footsteps falter in sync with his twin's, but he's quicker to recover.

"That's it," he agrees needlessly, staring. God, he knew it would be there, but--but seeing it now, even in the distance--

"You can't go in first." His tone isn't harsh to Seimei, but rather more matter-of-fact. His attention is still on the walls, and his hand twitches as if to reach out to touch them already.

"Even if there's something inside, that place belongs to us." He tears his eyes off the building in the distance to look to his twin. He's not wrong, right?
