Thanks for the Chapter When is the mc going to meet the Entity that sends him to the Avatar Universe? Maybe you should have him give to the mc Esdeath Teigu and Kuzan from One piece Hie Hie no Mi devil fruit. Esdeath Teigu if fully train could even allow him to freeze time and Kuzan devil fruit will make his body intangible and also have the property of Ice. This novel is called Cold Path, which means the mc cold or ice power should be stronger than any power he has or will have. It's something unique only to him. You could even have that Entity give Rukia zanpakuto from Bleach to him. After all, he is also a swordsman
