Characters you make friends with during your adventure will join you to help explore the dungeons.
Just like your character, your partners can equip weapons, armor, and charms. They can attack and use a variety of support abilities, so bring them along to make your adventure go smoothly.
...But if you're looking for a challenge, you can always try going it alone.
You can also give your partner 1 of 4 different commands to control their AI depending on the situation.
Work together with your partner and take on Gensokyo!
