Roommates Extra One shot [Toaru Index/Railgun]

Three Level-5s attending university, put on same class. What ever will happen between them (like an argue), it's always leading up to Level-5 difficulty.
This is side/ extension (One shot, non-cannon) story/ Fan-Fic for (non-cannon) Fan-Fic story named 'Roommates' from 'Fallen Angel Codester' (Lightly Alternated future time line.), that come to my mind, when no new episodes has been released. Let's hope we see some. (Dead fic on FanFiction.net)
Ps: Some 'stuffs' can be altered due to long time from reading this FF, reading light novels, and mi own fan-fics.
