Milly left the student council to focus in her career as a newscaster. Rivalz was asked to take her place as the student council president but it shows that Lelouch is the best fit for the position. Rivalz made a school festival on Lelouch's birthday, December 5. No one of them know about it. While planning for it, the Chinese Federation attack Ashford Acaademy and they are forced to stay inside the Clubhouse. Lelouch thought up a plan to defeat them. Lelouch's plan works at first but during the execution of the plan, Suzaku and Kallen's souls are taken in the 'Thousands-man vase' by the Chinese Federation leader. The other student council members hurried to the chapel and they saw the Chinese Federation leader. Nunnally and C.C.'s souls are also taken. Lelouch asked him to call his name, not as Lelouch but as Zero. When the leader is about to say his name, Rolo uses his Geass. Lelouch then uses his Geass to command everyone to wear Zero's mask and say 'Yes, your Majesty!' if Zero's name is said. All went as planned, but the vase can't handle many souls, the vase broke apart and the souls returned to it's own bodies. The student council members are left in the chapel, while Rolo, Shirley and C.C. vanished before their eyes. But Lelouch says farewell and thank you to everyone. Nunnally opened her eyes and saw her big brother and remembered, today is his big brother's birthday.
