This is the form where Mist Breathing's central metaphor pays off mechanically instead of just visually. Every earlier form describes what mist looks like; Scattering Mist Splash describes what mist does when something hits it — it doesn't resist, it disperses and reforms, and the individual bits of "splash" thrown off are, narratively, the attacker's own projectiles being turned aside. The panel bears this out literally: Gyokko's demon launches a spray of poisoned slime-fish, and Muichiro's single spinning cut redirects the entire swarm outward in one motion, rendered in the art as an actual whirlpool of scattered fish-shapes. VIZ's "SCATTERING MIST SPLASH!" preserves both halves of the compound cleanly, which isn't guaranteed for a three-word title under space constraints — compare how Form One's much denser classical allusion (垂天) had to be flattened into plain descriptive English.
飛沫 is a quietly clever word choice on Gotouge's part. It's not battle vocabulary; a modern Japanese reader more likely encounters 飛沫 in a weather report or (post-2020) a public-health poster about droplet transmission. Repurposing it for combat spray gives the technique a faintly clinical, almost scientific precision that fits Muichiro's characterization — a Hashira introduced as detached and analytical before his memories return, whose fighting style is described in-universe as unusually cerebral for someone his age.
Alongside Eight-Layered Mist (Form Two), this is the second of Mist Breathing's "volume" techniques — forms that manage many things at once (many layers of haze; many scattered droplets) rather than a single decisive line. The corpus shows both used back-to-back on the same page, immediately after Form Two, as Muichiro escalates through his numbered forms in sequence against the same opponent — a rare case in the corpus of two techniques from one style being demonstrated in a single unbroken combo, useful confirmation that the forms are meant to be read as an ordered set rather than a loose grab-bag of names.
