That Arnold guy looks tough. No wonder he's named after Pat Morita's character on Happy Days.
Holy bow, axe, staff, sword, shield, and spear... I feel like I've already seen the cartoon with the resulting classes: ranger, barbarian, magician, thief, cavalier, and acrobat. You just know that those weapons will end up in the hands of teenagers, too. If only that Arnold guy had wings and one horn, and rode a flying horse.
Considering how the cavalier was voiced by Don Most, I wonder what other Happy Days references will be in this manga?
