[Inner Sun]: Through meditative techniques, 自分 cultivates his inner heat, or as some would call it, Vitality. 自分 has cultibated this "Inner Heat" to the point that he has created a sun inside his soul [Furnace]: 自分 unleashes his inner heat to his sword, but instead of disintigrating it, it embraces it warmly, coiling around like Sword Aura. 自分 uses this to Shatter other Stars w/ greater heat
