Well this chapter kind of destroyed my faith in Irina. Instead of just talking to her daughter about facing Reona, she comes up with this convoluted plan.
If she did ask Hanako and she refused it's even worse as she is ignoring her daughter's wishes.
Either way she knows Hanako doesn't want to fight seriously.
Dragging Satome into this is even worse, it shows utter disregard for his feelings as well. Even if he gets a positive experience out of it, her motives were still shitty.
Also she already knows he has feelings for Hanako. She witnessed him giving her the present on christmas and knows everything he went through for white day.
I really hope Hanako calls her out on it. Only way to redeem this plot line.
