Touma goes along with it

So it worked! Touma thought, while doing his best to hide his surprise. He didn't want Misaka to get suspicious of him. Despite this, she noticed his eyes widen slightly.

Quickly, the look on her face became one of annoyance.

"What?" she asked. "Are you surprised I would make such a bet?"

"Ye...yeeah," Touma stuttered as he held up his hands defensively. He was glad that she didn't think she was acting strangely.

"Alright," Touma sighed. "I'll fight you."

"Follow me," she said as she turned around and started walking.
