Regarding its ending:
Ewwwwwwww...

Either way;
I'm not sure where to find the after story light novel (assuming there is no manga/anime ova of it of course)
Does anybody have a link to it? English please.
Would also need details, for example, to know how long this novel is. Afaik it's just a short story.

Yeah, there are like 5 extra stories in there, all occur 10 years later or so. Is that what I'm looking for?

If so, it basically means that there are no ovas coming.

Whatever, voices and stuff were good but thats what happens when you have a bad ending.
