Mousse personally wears a long, flowing white coat with elaborately large sleeves that cover his hands. It is unknown if this is a formal uniform of the style or not, but it clearly is very helpful with it. In Nihao, My Concubine he wore a short sleeved hooded shirt instead that did not impair his ability to produce hidden weapons.
As "generic" attacks, Mousse favors three in particular, depending on which form he is in. As a human, he favors volleys of chains or ropes attached to various weights, including sais, armored gauntlets, and yoyos, which he uses to entangle his foe and draw them closer. As a duck, he compensates for his reduced physical capability by throwing barrages of throwing knives and bombs.
Michi Bainiou Chuan ("Fist of the White Swan"): The attacker draws a swan-shaped potty from nowhere, hits their target with it at ultrafast speed and with considerable strength, and then makes it disappear again. Considered very insulting if the victim realises what they were just beaten up with. This is the first attack that Mousse displays and is considered something of a signature move, though he doesn't use it very often after Ranma first proves swift enough to catch it.
Michi Chitan Chuan ("Hen's Egg Bomb"): The attacker draws out a chicken that lays explosive eggs, which can be thrown as low-grade grenades. Mousse uses this technique during his first formal duel with Ranma.
Michi Inchua Chuan ("Raking Hawk's Talon") Affixing steel claws to the toes of his shoes, the attacker performs a diving kick onto his foe. Mousse uses this technique during his first formal duel with Ranma. In the dubbed anime, he claims that only one student of Hidden Weapons in each generation is taught this technique.
