Shining Heaven Unleash (天照界放;Tenshō kaihō) is a keyword introduced in BS51, exclusive to The ShiningHeavenDragonDeity Grand-Terasu, the Avatar of The Grandwalker Amaterasu.
The effect is worded as follows:
- Shining Heaven Unleash: 1 [LV1][LV2][LV3][LV4] (When Attacks) Destroy an opposing 20000 BP or less Spirit. Or, by putting one core from a "The Grandwalker Amaterasu" you control to this Spirit, during this battle, effects of opposing Spirits/Ultimates can't activate, and return an opposing Spirit/Ultimate to the deckbottom. This effect can't be prevented by opposing effects. When you've done so, this Spirit refreshes.
Like Creator Unleash and Absolute Unleash, this Unleash requires a specific Grandwalker to activate an effect much more powerful than an average Unleash effect.
