Oliver Aiku

Oliver Aiku serves as the commanding captain of Japan's U-20 national team and stands as the immovable cornerstone of its defensive line, widely recognized as the leading figure of the so-called 'Diamond Generation.' Of Swedish and German descent, he is also distinguished by his striking heterochromatic eyes. Having grown disillusioned with the football establishment, he transitioned from forward to defender. In clashes against Blue Lock, he erected an unbreakable 'last line of defense' through exceptional physicality and defensive intelligence, making him a pivotal force in shaping Japanese football's new era.
