But Indra is in Idiot ! He wants to fight against a God that faaaaaar supras him and could destroy the whole World. Shiva is on another Level and is the nearest to Ophis and Great Reds and Trihexas Level. And there are only few who has the Potential to reach the same high as The God of Destruction. Issei could reach it (Dragon of Destruction = DxD :D) and others i don`t know! Shiva should become Issei`s Sensei :D The Apprentice of Shiva : The Dragon of Destruction Issei Hyoudou :D have a nice Ring ;)
