'Twas... a day of wrath. The day when the holy internet was showered in a rain of blood. A single ray of light that purifies foolish lolicons to the very core of their bones. That, is the Ui beam.

This appears to be a dramatic and somewhat humorous statement, possibly referencing a fictional character or event. The tone is exaggerated and hyperbolic, using strong imagery like "rain of blood" and "purifies to the very core of their bones".
