Escort Nana to Mangetsu’s Hideout
Head to the Central Line to meet up with Nana. Take the portal to Middle Area Northwest Path then head through the nearby doorway to start a fight with a level 39 Giant-Headed Demon. It’s weak to ice attacks and drains fire and electric. Also, watch out for its attack that deals damage and steals MP. Once you take down the demon, continue following a path to the hideout to trigger a dialog event leading to the completion of the request.
