Glad you like the idea! Now the only problem is getting the dragons to show up. Touma can't just make them pop up whenever he feels like it nor is he ever gonna actually bring them up an any conversation. Touma pretty much ignores them. The only way for them to show up is to have Touma get his right arm severed. So, unless we can device a situation where that would happen, the dragons won't come out to play.
