The Gleam Eyes is a powerful minotaur beast whose physical power is beyond measure. You certainly don’t want to fight a foe like that without a plan. Luckily for Kirito, his twin blade style is more than a match for any beast and he can fly as well. This means that Kirito can just snipe at Gleam Eyes from a distance or use his superior speed to take the foe down. Either way, Kirito’s got this! Kirito wins.
