She's not saying onii-san, she's actually saying onii. Onii is an informal way of referring to your brother. It's translated because I felt it would be more important to get across that they're all still referring to him as their brother (and each do so in a different way).Would It really be bad If we went with Onii-san rather than bro since bro doesnt really fit the context
Nah, He's Rentarou's son. He acts just like him. A true chad who protects his harem and makes them happy. Plus those thick eyebrows, this manga is definitely inspired by 100 girlfriendsThanks for the chapter!
I trust in the power of those eyebrows to achieve the Harem ending, because every one of those girls is a best girl.
C'mon MC, make your ancestor Erwin Smith proud, Sasageyo!
