[LV1][LV2][LV3] Other than Soul Core, the opponent cannot remove cores from exhausted Spirits.
[LV2][LV3] Opposing Spirits that would be exhausted by your effects are heavy exhausted (Heavily exhausted cards are turned upside down and become exhausted after refreshing once).
[LV3] When this Spirit is targeted by opposing effects, by exhausting one opposing Spirit other than "The RichHarvest Koganehime," this Spirit is unaffected by that effect.
Ruling: This Spirit's [LV2][LV3] effect cannot heavy exhaust already exhausted Spirits.
