Blade towers duel enemies at alley intersections with iaijutsu draw-timing windows: fire right at the flash for a one-strike kill, spam and miss. Enemies can parry; per-strike rhythm matters. Signature: land three perfect draws for a combo screen-clear.
Neon Tokyo rain, magenta and cyan reflections on wet asphalt, glowing kanji signage, katana flash arcs.
