Once you reach Sendai, you can farm Bond Points at Mt. Aoba Park. During the day, visit the Fortune Box located to the left of your Camper. Buy a fortune for ¥100. You'll be granted a "Curse", "Blessing", or "Great Blessing" which increases your Bond meter. Fast travel to another area, come back, and repeat. If you're lucky and get "Great Blessings" you can level up Bond and gain points fast.
