Goura Hakone is the older brother of Yumoto Hakone. He helps his younger brother and seems to be a lot more mature. ~!It is revealed that he was a Battle Lover himself way before the 5 main protagonists became so. He was well known in the first CIDE battle as Maximum Gorar and wielded a battle axe. He saved Akihiko Beppu and Haruhiko Beppu in Binan Land from monsters leading them to have a deep fascination, deep obsession, towards him, which is both friendly and somewhat romantic.!~
