Sorry how close is the dynamic to those girls from avemujica? Because it's making me interested in watching it
Emma is way more mature than Uika. Uika is basically a big sad puppy following Saki around like she's her owner. Saki used to be like Suzu, but she tends to be a lot more hardass. Elaborating any more would be massive spoilers, so I'd say just watch Ave Mujica because it's a masterpiece. Of course, if you do you should watch MyGo first, because AveMuji is actually its sequel. It's also amazing.
