ok while the flipping back and forth could be annoying, and obviously i'm waaaaay too late to make any helpful comments on this story. probably one of the best uses of a rarely seen aspect of a crossover. it's rare that a crossover makes characters have to obey the rules of whatever setting they are put into, and rarer still for them to be remade to fit wherever they are sent unless it's just a straight Isekai (typically power trip) story.

No way...this is only the beginning?

Only thing missing now is for Touma to expand his harem to mlp girls...probably Twilight...and Luna for laughs. Loved number seven and pinkie pie moment. Keep up the good work!

I like how you resolved the issue. Like how this story combines the two worlds, the resolution is also one fitting for both worlds. It’s a pity this story seems to be nearing its end.

huh... I'll be honest this was way better than I was expecting for something related to MLP

Awesome! This chapter has a really great mix of action and funny moments. Especially Touma’s reactions to everything happening around him, Misaka’s reactions to all the newcomers and what happened when they met each other. Saten’s usage of Indian Poker was as a mix of both and you even gave Sphinx of all characters a Crowning Moment. You make really great use of the many characters in this scene. How they help each other, as well as how they hinder each other, even when they are on the same side.
And as an additional bonus, thanks to the many characters with different abilities we also get to see so many different spells used to counter them, a lot of which I can’t remember from canon.
I am really looking forward to the next chapter.

Nice chapter. I had completely forgotten to count the enemies, so intrigued I was with your story. Though I was wondering when those two would show up. And I really liked how he invoked mind magic and why he would know it, since it’s just so believable.

I am enjoying reading this, kinda surprised but it's a good read. Interesting how the characters interact with each other, but where is Misaka? I would have thought she found something by then or joined up with everyone else? Keep updating, can't wait for the next chapter.

Great story! I really like how you translate the characters from one world to another. Especially the abilities of the pony cast are really thought-through.
The interactions between the characters are interesting and fit very well within whatever world they are currently in.
The fights are really awesome written and fit very well with the spirit of To aru majutsu no index, with people trying to figure out each others weakness and attacking it. And like To aru, this isn’t only something the good guys do, making the villain scarily competent.
This story is also full of Crowning Moments of Awesome for a lot of characters in ways which I did not see coming and I enjoy them each time.
I can hardly wait for the next chapter to come out.
