Hesitation - S1.E10

The morning after Ruuji left, he still has not returned. Kotona goes out to search for him, and comes across him staying at the home of the man in the Zaber Fang-type who saved him from the wild Zoids. Kotona recognizes the Zaber Fang as Soul Tiger, and its pilot as Seijuurou, supposedly the greatest Zoid pilot ever. Ruuji begs Seijuurou to teach him to become stronger, and he agrees to travel together with them.
