Context: During Kichiro's first mission, he made a circuit: healing along every front as Konoha fought in the Second Shinobi World War. This is Katō Dan's opinion of Kichiro.

Medics are the most valuable ninja on and off the battlefield. That will forever be my opinion. I used to believe medics were the smartest and most talented ninja, until I met Uzumaki Kichiro, the so-called Spirit of the Triage and the only medic I personally knew who could rival (exceed) my fiancée's skill. I question the child's sanity.
The first strike against him: he doesn't know when to shut up. He deliberately antagonizes anyone who disagrees with him. I have no idea how he survived nine years like that. I was with him two weeks and I was ready to strangle the next word that came out of his mouth. Unfortunately, he was a medic and I very much wanted to avoid explaining to my troops why they wouldn't be receiving medical care.
Second strike: the kid is as clumsy as ninja come. Not even civilians trip over air as often as him. At first, I thought someone was pranking him because of how often he tripped, but either they were better than I could detect, or the kid was just genuinely clumsy. I asked him, and his reaction was: "Clumsy? Me? I'm not clumsy." I wasn't sure if he was being sarcastic or if he genuinely believed he was coordinated. I fear the latter.
Third strike: The kid spoke mixture of Japanese and English. He carried a conversation just fine, but he had a difficult time distinguishing between what he thought and what he muttered to himself. The kid had to know that any ninja worth their salt could hear him muttering, right? I was about to mention it when his sensei, Hatake Sakumo, pulled me aside. Apparently, the muttering made it easier to understand what was going through the kid's head. He had some very strange ideas. I'll approach him about the English bit when we weren't in the middle of figuring out a war with Kumo.
The kid was smart, I had to give him that. I doubted anyone, even Tsunade, could do half the things I watched him do. Unfortunately, the kid had enough stupidity to balance it out. Instead of joining his team and resting while he had the chance, he kept working. Admirable, but stupid. He managed to save some of the ninja we thought were beyond saving. They gave the Kumo nin quite the shock when they returned to battle, but I had to force the kid to sleep. By the time he left, I wasn't sure what to think of him.
I knew one thing: I owed the kid. If it wasn't for him, the war might not have gone as well as it did. Scratch that, the war certainly would not have gone as well as it did if we went without his help.
