Seeing Mira start to raise her rifle, Lyssa was presented with a choice. There were only a few brief moments to decide, but that was more than enough.
She could use her semblance and deflect Mira's shot with ease; projectile fighters were thankfully something that she didn't have to worry about too much. Of course, this would give up any potential to use it later for a surprise. That could give her the upper hand later on if things got bad.
The alternative, obviously, would be to take a straight shot from Mira's rifle. This would let her save her semblance, but in return, make it easier for Mithra to smack her into oblivion right off the bat. If she didn't get blasted by Mira, she would have a better chance against the giant hurdling towards her.
While the options were there, Lyssa herself hardly thought about it, almost immediately giving the slightest movement with her hand to create a large barrier formed from aura that appeared only a couple feet away. The bullet bounced off, but she didn't bother to watch as it happened, as she was preoccupied with stopping the titan in front of her.
With the length of Mithra's weapon, Lyssa couldn't hit her first, she was going to have to either block or dodge. Sadly, dodging was also out of the question, as blocking Mira's shot had kept her from having enough time to also move out of the way. Gripping her weapon tightly with both hands, she held them far apart, leaving plenty of space in the middle. Bracing herself, she thrust the middle of her weapon towards Mithra's blade as it swung towards her, only being able to hope for the best. Unfortunately, while her own incredible strength was able to slow it down some, it wasn't quite enough. The force from the swing was still enough to knock her back and take out some of her aura, the blow making her tumble a bit before she quickly got on her feet again.
"Noir! Get Mira!" It sucked that her plan hadn't worked out, as she really wanted to kick Mira's shit in, but it didn't matter now. She had to worry about her freakishly large twin instead. Hopefully, blind-guy would be able to preoccupy the bitch so that Lyssa could get to her later.
Yelling out, the red-haired woman suddenly charged at Mithra, starting to thrust the head of the glaive straight towards her center of mass. With the wind dust from before still in weapon, it would also release a large blast of air as she attempted the stab, the two attacks in combination likely being enough to move even someone of Mithra's size if it worked as planned.
