Zelda no Densetsu: Yottsu no Tsurugi+

During a stormy night, Zelda and the shrine maidens suspect that the weakening of Vaati's seal is causing strange occurrences. Zelda calls upon Link to protect her and the others as they open a portal to the Four Sword Sanctuary. A shadowy figure emerges from the portal—identified as Shadow Link—who captures the shrine maidens and imprisons them in crystals. Link pursues him to the sanctuary, where he acquires the Four Sword, a weapon that divides its wielder into four copies. Using this power, Link confronts Shadow Link. Vaati is freed once more and begins to cause destruction across the kingdom.
