Jin's outfit lets him resist the cold

After leaving Yabiko, Jin went to the encampment to collect his belongings first. Fortunately, the base was still there and his luggage was still intact.

Currently, they were in the middle of a campaign to bring down Wadatsumi Castle and there were few of their people left here, making it easy for Jin to get his hands on them.

What he took out was a blue outfit. The battle dress of the Kisaragi family. Underneath it, he put an inner layer designed to resist cold air. He also put on a pair of gloves that were thicker than his usual and specially treated to block out the cold air.

Yukianesa is an ice sword. If you are half equipped, you will freeze yourself.

But with all this, he is able to run while swinging Yukianesa around with all his might. No need of worrying about the damage to his surroundings and without worrying about his bloodflow.
