5

Maria stays with a girl named Yunyun in her personal houseboat a day after she wanders off in an alleyway without Canaan. Yunyun is later summoned by Liang Qi with a mission assigned to her. Maria and Minoru later investigate the T-shaped marks with the assistance of Japanese physicians back in Japan to study them and find out what has caused them for themselves. Canaan later meets Yunyun embarrassingly as part of the latter's mission is to get rid of her. Despite pleas from Maria, Canaan and Yunyun continue to face off against each other unsuccessfully with a plan by Yunyun to kill herself and Canaan with dynamite mounted throughout her entire body before Canaan decides to save the girl out of pity for Maria since she is her only friend. Back in Maria and Minoru's rented apartment room, Yunyun confesses to her true state as a Borner, but without any kind of special abilities granted to her by the Ua virus' infection since it merely gave her two appendixes. Minoru later pays him with money to help her be a double agent to both him and the Snakes as his personal informant. (Source: Wikipedia)
