Excel and Steiner, having arrived in Japan, conduct a covert mission to test Akane if she has strong Tera Energy flowing throughout her body. Later on, Akane meets with Keita and Kuro in a small restaurant after being followed secretly by Excel and Steiner from the local bank where she works as a bank teller. However, the three are ambushed by Tribal End bikers sent to apprehend Kuro and eliminate Keita and Akane. However, Kuro, failing to defeat the bikers herself, is intervened by Steiner, who then drives them away. (Source: Wikipedia)
