Oliver Aiku is a soccer player. Oliver can be bluntly honest and a bit reckless, but he respects those who impress him and maintains a competitive yet sportsmanlike spirit. He has heterochromic green and purple eyes. He's also known for his nonchalant attitude towards relationships, and he's a womanizer. Oliver lives up to his title as captain as he is the defender and peacekeeper of the Japan U-20 team.
