Uno is a fairly common Japanese last name. It has nothing to do with card games or the Spanish word for "one", just like the Japanese last name Soma has nothing to do with a Finnish word for cute (also soma). There are multiple languages but a limited amount of sounds we can combine to make words. So it's not strange at all that words sound like different words from other languages.
yep called cognates. sometimes the words have no relation and just sound the same. It's easy to get confused when the words don't mean the same thing.
Soy milk= milk from soy beans
Yo soy milk = I am soy milk
¯_(ツ)_/¯
It was a joke i know they didn't name him after the game but i didn't know it was a common surname because it's the first time i find it in a manga so i thought of it as a strange name
How can someone's name be Uno...like the cards game The last chapter was so funny and cute (≧∀≦) I loved it!
