I think the people here who don't know if Dante or Vergil are gay or bi are giving too much tought to the notion. All video game characters are straight by defult, unless it's ether specefied otherwise or we are told, namely because most videogames are designed to a demographic, young men. DMC and DmC are very much geared twards the boys, it wasn't till DMC4 that they wanted to shift twards female attention and even then they didn't make Nero's love interest another dude.
