The Yuzuki family's four brothers cherish each other deeply. Among them, the second son, Mikoto, dotes on Minato, the third son, while Minato, in turn, adores Gakuto, the youngest. 
Gakuto, I'm your big brother!
Gaku-chan, ich bin dein großes Brüderchen!
Gakucito, shoy tu hermano mayor.
Bonjour, Gaku ! Je suis ton frangin !
Gaku, sono il tuo fratellone!
Gaku-chan, sou seu irmão mais velho!
Гаку, я твой старший брат!
