Ep. 16: Para Pencari menyusup ke kediaman Kaidō untuk menyelamatkan Profesor Yamano dari Yoshimitsu.

Rina opens up a secret passage that leads to the yard of the Kaidō's. After they arrive in the yard, the Seekers groups breaks into sets of 3 to infiltrate the house. Lex, Rina, and Takuya head to the control center to open the door while the other two groups await to get in. Rina lets them in, and they decide to go to different ways hoping that one of the two groups can make it to the room Professor Yamano is supposedly being held in. As Ban, Kazu, and Ami travel they are seen by security and pursued. Just before they are to be captured when Kazu decides to tackle them down a set of stairs. Instead of being captured they roll into a secret entrance into the bedroom of Jin. Jin challenges Van to a rematch with his new LBX, the Emperor Mark 2. When the Emperor Mark 2 and Achilles both use their finishers, they knock each other temporarily unconscious. Jin is shocked that he cannot seem to defeat Ban, even with a new computer processor. Ban and his friends are able to leave Jin's room and arrive at the room Professor Yamano is supposed to be held in. When they arrive Van calls out for his father, and instead of his father Yosihmitsu appears. Yoshmitsu says if the group can manage to defeat his LBX he will give up Professor Yamano once and for all. A 3-on-1 battle is held, and Yoshimitsu wins with ease.. (Source: Wikipedia)
