If you have this card and "Snatch Steal" on the field, the opponent will take 1000 points of damage during each of his/her Standby Phases and you still control their equipped monster.
As long as this card remains face-up on the field, any effect of increasing your opponent's Life Points is changed to inflict the same amount of points in damage to your opponent's Life Points.
If you have this card on the field and activate "Rain of Mercy" you gain 1000 Life Points and the opponent takes 1000 points of damage.
The Continuous-like Effect applies while this card is face-up on the field. It does not activate.
If the opponent activates "Dian Keto the Cure Master", you can chain this card and the opponent will take 1000 points of damage instead of gaining Life Points. If the opponent chains "Mystical Space Typhoon" to your "Bad Reaction to Simochi", they will gain the 1000 Life Points.
This effect is not cumulative. If you control 2 copies of Bad Reaction to Simochi and your opponent activates Dian Keto the Cure Master, they only take 1000 points of damage [REF].
If the opponent activates "Nutrient Z" in the Damage Step, you cannot chain "Bad Reaction to Simochi" since it cannot be activated in the Damage Step. If "Bad Reaction to Simochi" was already active on the field, its effect would apply to "Nutrient Z".
VS. Prime Material Dragon: if both Bad Reaction to Simochi and Prime Material Dragon are on the field when Player A's Upstart Goblin resolves, Player B will gain 1000 Life Points (gains / damage happen normally) [REF].
Multiple copies of this card are not cumulative. If you have 2 copies of "Bad Reaction to Simochi" on the field and the opponent activates "Dian Keto the Cure Master", they only take 1000 points of damage.
These rules apply similarly to Nurse Reficule the Fallen One (erratum: Darklord Nurse Reficule).
If you control this card on the field and activate Rain of Mercy (which makes both players gain 1000 LP): you gain 1000 Life Points and your opponent takes 1000 points of damage.
