Trinity Seven

A blonde-haired character with purple eyes appears in a dimly lit stone chamber, then the scene shifts to a smiling silver-haired character with pink hair ties, followed by a rapid motion blur, a close-up of the blonde character's face with a faint smile, a character with long pink hair and a glowing chest against a starry background, and finally the blonde character looking down with a surprised expression as a bright light emanates from below.
