"And don't worry, she won't die of over exhaustion, she will simply pass out. It won't shorten her life or anything." He continued, trying to clear up the whole 'giving your life up' thing that has aroused thanks to his explanation. He then smirked at Casper's observation. "You have keen eyes Casper, I like that." He said before looking over at Arisu, noticing that she was slowly transforming because of the cold. He took his lighter out and then used the heat coming from that, intensifying it and making it spread over to the group so they wouldn't feel cold. This did not include the fire though so it was perfectly safe. "Better?" He asked Arisu.
