While Tsunade watched, Naruto argues to Ay about his wanting support his friends who are fighting for him. Ay berates Minato Namikaze and Naruto tells that his father is not a failure, attempting to outrun the more faster Raikage. But Ay decides to simply kill Naruto with Bee quickly saving the younger Jinchūriki. Bumping fists soon after, Bee asks Ay why he can't read his soul and recalls their past where Bee became Ay's brother after passing his Double Lariat test. Their bond improves as they go on missions together prior to A receiving advice from Bee's cousin prior to his death and Bee becoming the Eight Tails Jinchuriki. Now a fully grown man, Bee and Ay encounter Minato. Ay makes his speedy attack however Minato evades and tries to land an attack on Ay's back but Bee's tentacle quickly saves Ay. As the Leaf group retreats, Minato compliments Bee's ability. Ay berates Minato and charges toward him but Minato teleports to Bee's back pointing at each other with a weapon.
