After learning that his grandfather, Jin Taejin, has been confined, Mori rushes to set him free. Daewi and Mira await his arrival at the tournament with no idea what's going on. With Mori missing and Daewi suspended, Mira is forced to kick of the team match alone. She struggles against her opponent, Marin, who evades her attacks and counters with her own sword. When he calls it a National Treasure, it begins to glow white, and its true form is revealed...
Born and raised on the sea, 
the marine marvel, Lee Marin,
،وُلد وترعرع في البحر
،الأعجوبة البحريّة، لي مارين
Im Meer geboren, im Meer aufgewachsen,
der wunderbare Meeresjunge, Lee Marin!
Soy un monstruo marino
nacido y criado en el mar.
Soy un monstruo marino
nacido y criado en el mar.
Je suis le prodigieux monstre marin,
né et élevé en mer,
Nato e cresciuto in mare,
il miracoloso prodigio degli abissi,
Nascido e criado em alto mar,
sou Lee Marin, o prodígio marítimo!
Родился на море и на море же вырос!
Я чудесный морской монстр Ли Марин!
