If I may jest a little, Kuroko (a known pettanko-yuri) gave priority to the two girls with the smallest bust and potential romantic interest
In general, the episode was entertaining; priceless Index VS Mikoto! I also kind of like Cromwell's feminine adaption (though it can be
another trap), as for Touma's power, I will abide to the
plot device explanation.
Oh, I should not forget, I love Hyoukka (meganekko X oppai). As for how hooking with Touma could work, they can always get a little kinky, none-the-less safe by chaining his hand during intimate moments
