Its really depends on what "related" is supposed to be mean, either actually biologically related or "related" in a contextual sense. Indra is more related to Shiva than say Zeus would be in a story-sense. Plus, it makes little sense to make some random Hindu god a villain when the foreshadowing of the conflict between Shiva and Indra is volumes in the making, as well as Indra's contempt for Issei. In all likelihood Indra may lose this tournament and declare war anyway, leading to the Shiva v. Indra war that's been hyped up for the last ten something volumes. Besides, with Cao Cao as Indra's vanguard, we will probably see a rematch in Issei and Cao Cao is such a thing happens as well.

I think that things are shaping up for him to fight Indra. Not only is there some subtle aggression between the two, but I feel Indra is cocky enough that he could be the first god Issei beats, starting Issei's reputation as a "god-buster". Who knows, Indra may underestimate him in the tournament a get beat by like AxA or ExE, and then the final battle is Indra going all-out, without the rules of the Rating Games to restrict them.
