When she awakens from her dangerous solo mission, Yuri finds her surviving friends in Battlefront seem to have found peace. In an impromptu "graduation" ceremony, they all take steps to move on to the next level of existence. But this transition seems most difficult for Otonashi, as it means losing his newly formed bond with Angel.
 

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 Tenshi wonder what is happening and lead them straight to God, threatening the others with no food for a week if they fail.
