Does Evelynns(Gym lady) path end after I tell her about sumo or does she have more after
She has a whole arc of gaining even more weight. After she excitedly tells you she has embraced sumo as her new goal in life. Check out the buffet every once in awhile to progess her weight gain the next time you visit the gym. It ends with her participating (and winning) a sumo tournament. There are roughly 25+ additional images in her arc.
