any idea how to edit the body hair options?
After a couple of days the mirror in her room should be sparkling and the option to edit body hair should be available. It's not unlocked from the beginning.
Also, NONE of the quests are translated, so good luck making sense of where to go and why it's not letting you pick most of them. For those wondering, the majority of quests seem to take place in the Clubs area of school, the exit to the right after you enter the school building. The dialogue with the NPC is at least in English so i recommend not skipping through it if you want to know what you're expected to do.
Lastly, quest wise i can recommend grabbing the quests that list "Lotion" (+12 attack), Girimosa Earring (+6 Defense) and Urinal Charm (+18 Defense) as rewards. They're available right after joining the Student Council after the first bossfight, and they're all Accessories that boost your Defense up by about 50% compared to your regular numbers and the Attack increase is nice too. I'd tell you which ones they are, but yeah... untranslated. You can see the rewards of each quest before accepting though.
The bossfights i've run into (School Council members) seem to rely heavily on being able to outheal their damage output, so i can recommend saving up for the skills at the shop that heal 30% and 50% of your HP per use (at no cost other than spending your turn doing it) and can be used out of combat as well. If you need to grind, a number of areas have roaming enemies that respawn when you leave and reenter, just run up to them and if running into them doesn't triggger combat they're just the type you can talk to, usually for a molestation.
