The second law of the "Sin-Cleansing Punishment Tower": the confinement effect directed at spell targets.

The final, decisive effect of the "Sin-Cleansing Punishment Tower."
Once every target had taken their place in the subsidiary towers, Sainsai, standing atop the main tower, would use his own mental power as fuel to summon the grandest flames for every
