Its time to use this thread for what it was made for.
As part of the Kamachi Kazuma 10th Anniversary Celebrations, Kamachi wrote a short story that was released a prize in the Ichiban Kuji lottery (Announcement #5).
The short story is titled
Toaru Hourou no Imagine Breaker or
A Certain Wandering Imagine Breaker. For a while, we had no details about the contents of the short story. Luckily, Debi from
Trigger Happy End made a blog post about it
here. (Its all in Japanese though. Also, no pictures for the SS).
The story occurs in the first 10 days of September (again) putting it somewhere between OT6 and OT7 (or between the 2 anime seasons if that's how you remember it
). (My guess is that it occurs on September 6 or 7th considering there is no other time that this could occur).
In a nutshell:
1. Someone is setting up a magical attack against Academy City (again)
.
2. The thing that will become the key for this attack is
Kamijou Touma's sleeping time.
3. After this,
within a 5 hour time period, if Kamijou is not sleeping for at least 2 hours (ie awake for 2 hours or more) the magical attack will commence! (I'm guessing this repeats every 5 hours. Don't know how this works so don't ask. Also: Fukouda!
)
4. Because of this,
Kanzaki Kaori arrives to put Kamijou to sleep.
Other characters who appear:
Index (obviously);
Himegami Aisa (hooray);
Misaka Mikoto (obviously) and
Shirai Kuroko (seriously).
Comedy and potential jokes about sleeping in the same bed together are bound to occur.
As for the effect of the magical attack in question, I don't know if Debi is trolling me or not so I'll wrap it in spoiler tags:
Hoping that more details can come from a better translator (and that js06 will get to this).
