Serena y Seiya En el avión

In Sailor Moon Stars, Serena follows the plane to warn Seiya that they are in danger, but no one believes her. Amy, Rei, Lita, and Mina watch as Serena stays behind with the Three Lights. Seiya asks Serena how she got the ticket, not understanding anything she says, but assures her that if anything happens, he won't let anything bad happen to her and will protect her. Serena blushes and sits next to Seiya during the night flight, worried and afraid of what might happen; she herself would feel guilty.
