Goddamn, I love this chapter.
The tension, how they use tactic to one-up each other, showing their thinking process, damn, giving the spotlight to someone that's not a level 5 that can simply overpower anything is truly the right choice.
Then the prism she use at the end that seems to be the same method Meltdowner use to disperse her attack, and then her goal that seems like to be a callback to Accel's Level 6 project, that is, sac-ing herself to level up Junko...
I can only get so hard, c'mon.
Iruka's a good girl.
I honestly wish she survives this whole ordeal intact.
