Summary
A winter fairy of European descent. He leaves ice patterns on windows and nips people's noses. Though normally an innocent creature, he will freeze his victims to death if provoked.

Elemental affinity
Weak to:
Fire
Official data only distinguishes Weak / Resist — it does not separately flag Null, Repel or Drain like some other Persona games.
Battle Mechanics
Jack Frost will not attack unprovoked and cannot be defeated. When damaged, he immediately uses Bufu on the attacker, dealing a small amount of Ice damage.
Non-combat mascot encounter — invulnerable by design (game data has no HP-kill path for this sn), not a data gap.
