Unassailable:: 自分 is untouched by impurity & hostility
Outsider:: 自分's incomprehensible even to 相手
Ineffable:: 自分's intent is unknowable & above 相手
Absolute Mystery: 相手 can never hope to understand 自分
Effortlessly countering 相手's attacks & abilities, 自分 wears a comforting smile as if consoling 相手's soul, his figure always out of reach, so close yet so distant as if unassailable to all forces whether natural or supernatural
Such is 自分's dignity, his Sword Art, always remaining distant, his intent unknown as he gazes beyond 相手, to an incomprehensible & ineffable goal/future or whatever it is
