Over on the frozen lake, something cracks a few paces before Cirno's feet as the gigantic laser beam flashes towards her. At the right moment Cirno raises her arms in a manner resembling an attempt to block a punch and a huge slab of ice from the lake rises up at an oblique angle, allowing the beam to hit it at an angle and showers the area with ice shards as the slab gets thinner and smaller.
"Gwoah....argh..." grunts Cirno as she holds her hands up at the slab of ice in an effort to reinforce the cracks and missing bits with more ice.
"Just...a little bit more..." Cirno strains after what seems like an eternity of being under the blast ray of powerful magic.
"AHHHH!!!" Cirno roars as she feels the magical assault begin to soften up. Drawing a small bit of extra energy, she shoves the now barely man-sized slab of ice forward and ducks down as it explodes, sending more showers across the frozen lake surface, even the hole where the huge slab originated from quickly froze over from the mist.
"You...you're good...my...turn. Ice Sign! Icicle Fall!" smiles Cirno as some smoke from the after effects of Marisa's attack singed her. Raising her hands outwards, shards of ice formed from the gathered water vapors and mist and begins to fire outwards and forwards. Each shard is as sharp as a flint rock dagger as it flies true outwards. A pretty dense danmaku of ice flies towards Marisa, some pieces hitting the icy spell barrier and drops onto the ground, others rebound with the right force and angle to come flying towards Marisa from the back.
Strangely enough, there is a large gaping hole in front of Cirno where no ice shards fly through.
