Bruh.. She's literally built like that..
Tsunade literally has no muscle. She's strong bc of her chakra and her being a fighter means nothing. Mei is a fighter, means nothing. Samui is a fighter, means nothing. Hinata a fighter, Sakura a fighter, hell, even most male characters in the show aren't even that jacked besides Bee and Raikage.. Y'all nitpick every time something is shown.. Y'all gone be the reason this line gets dropped.. THEN complain about that too..
Get your figure a different body then. I'm taking all of these as they are bc I'm glad they're even being made in the beautiful quality we see today. BigTrunten out
