Acidic Secretion Technique

This is a technique created by Kuro Isei at a fairly young age of 14. It allows him to secrete and acidic liquid from every pore of his skin. The acid is highly corrosive, in fact its so corrosive that it can melt throught the most solid metals in the world. This is extremely useful for an array of situations. Due to this any taijutsu attack to land on him is extremely painful and will burn the attackers point of impact. Even if the attacker hits Kuro's clothing they will still be burned as the liquid goes through is clothing. Furthermore he can secrete it as a acidic vapour around his body similar to a 'Chakra Mode'. If he wants to he can extend the radius of the vapour. He can imbue the vapour version around any of his other chakra modes or armours (Including Susanoo).
