Showdown (ケッセン Kessen) is the 2nd episode of the Amagami SS+ Plus anime series.
Tsukasa sees Noriko about to kiss a panicked Junichi and angrily drags him to the Janitor's shed which Noriko believes her plans have work. Instead, Tsukasa kisses Junichi to calm him down, revealing she was aware it was a trick by Noriko to cause a rift between them and makes Junichi promise not to fall for Noriko's tricks or kiss any other girl than her. On the day the candidates give their speeches, Junichi and Tsukasa's supporters give Tsukasa a sash with their signatures and supporting words for her. As she goes on for her speech, Junichi comforts a nervous Tsukasa who goes on to give an inspiring speech to the students. Tsukasa wins the election by a landslide while Miya and Ai celebrate Sae getting second place and overcoming her shyness at a Karaoke bar. Noriko, distraught by her loss, vows to her friends she will beat Tsukasa and steal Junichi from her in the next election. On the way home, Tsukasa and Junichi encounter a stray dog chasing them. Junichi attempts to ward the dog away only to fall into the river. Drenched, Tsukasa takes him home to clean him up in her bathroom, just like the dream Junichi had before except Tsukasa is cleaning him in her swimsuit. As she washes him, Tsukasa thanks Junichi for being with her all this time and reaffirm their love for each other and kiss. With the new school year starting, Tsukasa and Junichi begin their duty as student president and vice-president together.
