GTO: 14 Days in Shonan Vol. 4 (manga)
This time round the GTO has a special case. He's got a good kid to look after. Seiya has his head on straight despite having a troubled home. And if there is anything the teen struggles with it possibly is how badly he wants to fix his family.
Like many single-parent children, Seiya has an attachment to the lone parent that has been around. And even though this person has neglected him enough that he is now in child protection, Seiya's willing to risk his future and maybe his freedom to make things work out for his small family. If that means taking arms, then so be it!
But the GTO is not going to let him off easily. You cannot pack heat without getting burned in his town! So Onizuka is going to show him what it means to shot someone. He's gonna let him experience being hunted down. The school of hard knocks is back in session!
