Whose you're hero?

Its the hero in the left slot of team 1

The leader of your first team.

What is indeed a hero? does man become one because of his righteous actions? His ideals? or does one become when he faces evil?
we yet do not know.

But what is a man? A miserable pile of secrets! enough talk have at you!
(sorry for the bad reference joke)

The "main hero" is the one on the left most side of the 1st team and the one you summoner support is your Waifu/Husbando.
