Cirno's Spread Shot. Her bullets shoot out icicles. Don't underestimate the attack just because the bullets are made of ice. The frozen water is as hard as metal.

Cirno's Focus Shot. It freezes anything it touches, so you definitely don't want it to hit you. It is unclear how the freezing laser works and what temperature the laser is. Knowing Cirno, it could be -100,000,000 degrees.

Cirno's Spell Card. This bullet attack generates a large number of icicles and lets them fall down on its target. It is a terrifying sight, to say the least. If you look closely, you can see that the icicles never fall near Cirno.

Cirno's Spell Card. After letting loose a barrage of colorful bullets, Cirno freezes them to a stop before making them move again in this elaborate attack. Anyone who underestimates Cirno for being a mere fairy will regret it―in spades.

Cirno's Last Word (a Touhou LW original). Cirno puts all her power in this attack―like she plans to freeze the whole Earth―to freeze everything surrounding her. Water expands when it freezes, so the ice on both sides grows to crush the targets between them. All Cirno is doing is chilling the area around her, but that is enough for her to wreak all this damage.
