June brings the rainy season to Inaba, which affects Social Link availability and can sometimes offer unique activities. The next victim, Rise Kujikawa, will soon appear on the Midnight Channel, leading you to her unique dungeon.
With Kanji now in your party, you have a powerful physical attacker. Continue to prioritize Social Links, especially those that are only available on specific days or during certain weather. Rainy days are excellent for studying or reading, as many Social Links are unavailable.
