Blue Seed (1994)

S1E10 Innocence! Love! My First Kiss?!

Tokyo is once again under threat from an Aragami, this time a fire-breathing frog targeting the subway system. During an encounter with the creature, Momiji crosses paths with Muramuko, a sinister figure who nearly takes her life. Just in the nick of time, Kusanagi rushes in to perform mouth-to-mouth resuscitation, which Momiji interprets as a kiss. He then steps up to confront Muramuko in a tense showdown.
