Galaxian had hugged back, but as soon as he felt the other force on his ankle, he let go immediately, somehow having realized that just as he couldn't wrench himself free without losing a foot, he also couldn't pull Kenshin with him. His eyes, which had been closed, shot open, looking around for a potential escape, but he knew the situation couldn't be any different, at least for him. From just fighting in the battle at all, even though the deity had not killed anyone himself, he had been fighting unconsciousness throughout, and unfortunately, that unconsciousness was trying to get him right now. Just that meant he didn't have the strength to struggle at all.
He also realized that somehow, once again, Kokumajutsu was still alive. Which was humorous to him, somehow, so he smiled--at Kenshin, and anyone else who could see him at the moment.
I mean, he thought to himself, I should get the chance to smile sincerely once more before I have to fake them at Koku, right?
