Not Guts on Page 3. The sword is wrong. Dragon Slayer has a round connection at the top of the hilt and a single chain link in the center. That is a straight edge connection. Also, it's tiny in comparison to Guts' Dragon Slayer. If you include the hilt, it's taller than Guts. The sword as shown is shorter than a seated person.
Probably a generic Heavy Warrior type, makes sense for them to carry throwing knives to attack/wound smaller faster enemies at a distance. Then close in for the kill.
