Realism? You mean like deaths? Well, considering Oda's history prior to Wano, it was very unlikely to happen. Man, I am so dissapointed with Oda sometimes, he has (had? ) the skills to craft a good story, but not liking to kill characters offi in a war against the WSC and his crew is just weird.
Tama, what a character.... I hate that girl in every possible way. A walking plot device protected with tons of plot armour. Momo was enough, another kid wasn't needed at all this arc.
