How Mito would be, if she fought someone when highly upset? (Plus, other’s reaction to it)
Usually she would be calm and composed, but if the other one would had gotten underneath her skin…well, people would then at least know she is a true Uzumaki. Seriously. Don’t be near a pit. Mito will kick you in there and you’ll regret it.
How others would react to this?
Hashirama would be extremely proud of his wife. He would just watch at the sidelines and cheer for his wife, until the fight would be over. (Which would be quite soon.) After this he would walk up to Mito and give her sweetest kisses to her cheeks and lips, whispering to her how proud he is of her. He would be just mostly quietly, yet there would be this certain glint of proudness in his eyes.
Tōka would break out the good popcorn to watch the whole thing go down. She would be highly entertained, since it’s actually quite rare occasion when Mito just gets so fed up she resolves into violence. So, it’s worth to watch and chill. She would also stay to watch Hashirama smooth over Mito, because things would only get more heated up afterwards…
Tobirama would just be standing off to the side with his arms crossed and a single tear in his eyes saying, ‘That’s my sister-in-law’ while being extremely proud of her. This man might not show many emotions, but when it’s about family…even he will display some. After the fight he would just linger there, while there would be tiniest smile on his lips. But if someone asked him about it afterwards…he would deny such a thing.
Madara would be most vocal when expressing his feelings. He would clap, cheer and maybe even slip few times ‘-ll it with fire!’ when Mito would fight. After she would had won, he would end up into applauding and shouting ‘see this woman in here? She is my best friend!’ Madara knows how to pick his friends and how to be a best friend.
Izuna would had been making bets at the sideline and afterwards would collect quite hefty sum of money from his betting. After all, he would had known Mito would win and how she would had won. How is that even possible? The other people who made bets with Izuna will come after him after the fight has settled down, but by the time they go after Izuna’s neck he is already long gone.
