OverwhelmingAura: 相手's attacks are rendered obsolete
Overwhelming:: 相手's defences are obsolete before 自分
Absolute Power:: His presence is immutable & overwhelming
Indomitable Will: 自分's will is unbreakable/incorruptible
Truly Immortal:: In battle, 自分's life is unassailable
[Sky Manifestation]: A vast expanse of sword aura, qi, & mana overflows into 自分's blade as 自分 unleashes a strike—no, the entire sky at 相手, his Overwhelming Energy replicating the [Infinite Horizon], leaving nothing in its wake.
[Obsolescence]: At the final clash, 自分 stabs his own heart as blood akin to the night sky flows to his blade, as 自分 unleashes [Sky Manifestation] on 相手 once more.
