To strip Angel of her scholastic power, Yui devises a plan for the Battlefront to replace Angel’s test results with bogus ones. She will be shamed, stripped of her title of Student Body President, and be out of their way for good. But they never realize the one who replaces her may be even more sinister than Angel could ever be.

Set between episodes four and five, Yuri comes up with 'Operation High Tension Syndrome', encouraging the other members to behave as wildly as possible, so they would appear to be enjoying school without disappearing. Yuri hopes this will make Angel wonder what's happening and lead them straight to God.
