i already lv 3 agility and she doesn't give me the aptitude quest, she keeps telling me to come back tomorrow as i am ready but the quest never updates, it's there any other hidden trigger to this? or i am just bugged?

Have you tried all different options when talking to her? I think it happens just from taking to her, but I'm not sure.

i did all i could, if i talk to her she says i need to get lv 3 agility then train with her, so i do that and she says i am ready to do the training i should come back in the next morning, i do so, she just trains again normally and says i am ready, come back the next morning, i am lv 5 agility now and nothing. i exhausted all possible dialogues nothing, i will just restart a new game and see if it happens again

Talk to Haru during midday and she will test you
