Battle Tendency - Chapter 57 
The two warriors are about to begin the second lap, with Wamuu in complete shock. The vampires ready the second weapon, two steel Crossbows; one big and the other small. These crossbows are powerful enough to crush Wamuu's skull if he is shot in the head. To overcome the shock, Wamuu activates his "mental switch" by gouging out his own eyes. From his forehead sprouts a drill-shaped horn. With this, Wamuu will be able to "see" by feeling fluctuations in the wind. The two warriors reach the second lap. Joseph grabs the larger crossbow, while Wamuu grabs the smaller one. Joseph tries to use the crossbow, but he is not strong enough to cock it. To figure out the distance between the two, Wamuu fires a shot, obliterating the head of Joseph's horse.
