Set several days after the "World Purge" chapter, Infinite Stratos 2 has players developing relationships with the IS heroines as Ichika Orimura. "Braveheart Points" signify Ichika's manhood, and will fluctuate depending on choices made during conversations, with endings changing as a result of the final value.
In addition to chatting it up, Ichika can give the heroines a massage to deepen their bonds and increase Braveheart Points. Techniques involve tapping and rubbing properly, though, so you can mess up and fail, losing points as a result.

Walking home after wrapping up the enrollment procedure at their new school, they noticed a large truck stopped outside of their house.

Instead they found a girl pushing a giant piano with all her might… while in her underwear. They stood dumbfounded at the absurd sight. Why was there a half-naked girl in their house? Soon she noticed them and yelled at them to get out. A few minutes later, she came out in a beautiful dress.

The only thing I can remember is coming to in the middle of an unfamiliar snowscape. Where that was or how I got there, I don't know. I couldn't even remember my own name. The memories just wouldn't come.
I only had a moment, left at a loss, to ponder what to do — but fate seemed intent on furthering my misery as a giant, insect-like monster burst from the snow and ice to attack me.
Naturally, I ran like hell. The creature cornered me anyway.
That's when SHE appeared, as if from nowhere — the beautiful, mysterious girl who saved my life.
She told me her name was Kuon. A beautiful, mysterious girl...
...with a tail and ears like a beast's.
