Hikaru is one of the founders of Kaiho, the army of Light. He is the strongest and most skillful of the remaining Kaiho captains, and his skill with his dual swords is well known and feared among Kaiho’s troops.
As with the other captains, he is an expert in the usage of Light essence. Thus, he will be the most formidable foe you will encounter when it comes to close quarters combat. Knowing that, you will probably want to stay away from his weapons’ reach.
