Episode Title:
Dad Gets Trapped
Episode Description:
As Grace and Anna enter the secret vault to meet up with the student council, the boys vanish after Lucas solves a Rubik's Cube puzzle. Soon after, Grace and Anna exit the room and find themselves in the Labyrinth of Trials where the two must solve a series of riddles with one of the boys. The first riddle with Virgil has Grace using Orion's fire and water magic to create a bath in a small tank. Afterwards, Virgil returns to the cube and Lambert comes out for the next trial centered around the Riddle of the Sphinx with each person simultaneously standing on the designated number of legs and shouting the answer, which relates to a human's lifetime. As Grace and Anna move in for the third trial, Hinako explains that this event is a bonus game designed to boost intimacy with random characters that most players skip due to the difficulty of solving the cube. For the next trial, Pierre is tasked with making an ice barrier around a ring to light a torch using the sun like a magnifying glass, but is too afraid of heights. Instead, Orion uses water magic to create the barrier to clear the trial. Richard and Auguste come out for the next trial, based on the fable The North Wind and the Sun with Lucas being the traveler. Richard brings out a taiko drum, but being terrible at singing, Grace plays instead. Grace uses Kenzaburo's experience with rhythm games and karaoke to sing the ending theme of Galaxy Express 999 to get Lucas to come out and pass the trial. Afterwards, Orion (controlled by Hinako) grabs the cube and takes it apart for Grace and Anna to reconstruct piece-by-piece like what Kenzaburo once taught Hinako, but the cube reverts to its previous state; it will not allow cheating. However, Anna solves the puzzle to bring everybody back to the secret vault.
