Synopsis
A certain unlikely hero…
Only Komoe’s class would let a regular conversation spiral out of control into a grand-scale hot pot party. It’s an open question whether her students are a blessing or a curse. Meanwhile in London, the English Puritan Church’s facilities should generally be a place of prayer and quiet contemplation…So who’s going to take responsibility for the chaos unfolding in the sisters’ dorms?! Back in Academy City, a certain railgun’s mother has suddenly popped in for a visit, which is more than enough to make even a Level Five esper panic!

a question please why you didn’t put this novel into the toaru majutsu no index page since this is part of that novel ?
I don’t read this so I don’t know. And YP separates the 2 under a different series page, so I followed that.
