Lore:
When a Spirit monster is returned to your hand at the End Phase, you can Special Summon this card from your hand. Once per turn, you can equip this card to a Spirit monster you control OR unequip it to Special Summon this card in face-up Attack Position. A monster equipped with this is not returned to the hand during the End Phase and gains 400 ATK. If a Spirit monster is returned to your hand while this card is face-up on the field, return this card to your hand. (A monster can only by equipped with 1 Union Monster at a time. If the equipped monster would be destroyed, destroy this card instead.)
