Children
Kaku managed to always hold his head high. No matter what happened.
Even if he happened to eat a Devil Fruit that would make him a very square giraffe that no one could look at without bursting into laughter, he managed to hold his head high.
Even if he would lose to a pirate swordsman who only used santouryuu compared to his yontouryuu, he managed to hold his head high.
Even if he had to be a slide for children in order to collect enough money...
...he had to hold his head high.
"Gyahahahahaha! Bye then, Kaku! We're going to go see Lucci in the hospital, be a good boy and wait there!"
Kaku fumed with rage. He didn't usually get this angry this easily, but never in his life had he sunken so low either! A terrifyingly huge group of children, even more than there had been in the city, was climbing on top of his head to get on his back and slide down only to return back so they could climb again. Some of them even grabbed him painfully on the ears, but Kaku had to force himself to be quiet. These are innocent, ordinary citizens was Kaku's mantra, which he used to keep himself docile, even though he definitely didn't think of these children as innocent anymore. Attacking them is forbidden.
"Thank you for letting our kindergarten rent your giraffe for a while", said a young woman to the other members of the CP9 standing on the outer side of the fence. "He was so popular among the children in the city, they absolutely demanded that he come here as well!", she smiled. "He's amazingly tame too!"
This provoked a cheerful reaction from them all, especially Jyabura. "No problem at all, it's always a pleasure to help other people, isn't it, Kaku?", he added, looking at Kaku with an annoyingly victorious expression on his face.
Kaku shifted his gaze on Kumadori, who had to hold his hand against his mouth to prevent himself from laughing. "Yo-... Yoyoiii! We shall be back soon to collect you!", he could just barely say through his fingers.
Blueno in turn had a lazy smile on his lips, which was almost the same as if he had laughed hysterically. Fukuro looked just like he was going to tell half the world about this. Kalifa's eyes couldn't be seen under the glasses, but Kaku could clearly see that she was trying to hold back laughter. Kaku was immensely thankful Lucci wasn't present; he was so sure that even Lucci, whose face was usually completely emotionless, would've worn a predatory grin, and that was something Kaku would definitely not have been able to take.
He fixed a murderous stare on all of them that was supposed to say: You will all pay for this.
Still laughing, Jyabura motioned the others to come with him. "Let's go! They said Lucci's just woken up and he's not the patient type, like you very well know..."
And make sure to come back at the speed of lightning, you bastards!
Yes. It was a well known fact that Kaku managed to always hold his head high. No matter what happened.
