Well, he was expecting a pummeling to come his way with how exposed he was. However, there was little the young rapper could do against a direct shotgun blast like that. The shot hits him but he's just slightly more prepared for the oncming swing as he places Flow in between the attack and his poor, defenseless chin.
The attack still sends him back - again, it feels as though he may have let it do so on purpose as he uses the small break he gets to slap Soul into Flow in order to assemble Encore. A grin appears on his face as he places the mic up to his lips, activating his semblance once more.
"I may be shit outta luck, might be jolly-well fucked," he shouted as he dug through his pocket to produce a small, turquoise-tinted dust cartridge - he was hoping the shouts would keep Jima back long enough. He slapped it into the mic before shouting again, releasing "but i ain't gonna stay stuck, 'cause I hit like a truck, no dog - more like a buck, with my feet in the muck I ain't givin' up!"
As he would yell into the microphone the force of his semblance would then be accompanied by an ice-cold wind and a flurry of snow, sizzling as it fell across the lava behind the fighters. The effect wouldn't last long, but it would have to serve its purpose for Rufus to succeed - to deal some damage and to slow Jima down.
(Ice wind lasts as long as it remains uninterrupted. 3% damage per second in it, with metal objects, clothes and any loose things possibly freezing solid.)
