Looming Sword: His sword casts protective Shadow Wards
Shadow Wards: Protect 自分 from all types of harm/dmg
Shifting Shadow: Evades through gaps in 相手's perception
Zero Waste: Allows 自分 to fight endlessly w/o tiring
Shadow Incense: Slowly seals 相手's power & bizarre skill
自分 does not targe his foe specifically, but rather their inner darkness—the fundamental flaw/evil that exists because nothing that exists can be perfect (regardless of what your ability or you call yourself)
This fundamental evil is perceived as a shadow by 自分, & by hitting it he causes resonance, also damaging his foe
This ignores defence/evasion/etc since 自分's directly attacking their shadow
