Story

Under orders of Mou Bu, Ko Zen raised Mou Ten since the day he was born, developing a loving relationship with the young heir of the Mou Family to the point that he was fondly called "gramps" by him.

Third Faction Arc

Ko Zen first appeared commenting on the competition for achievements between the Hi Shin and Gyoku Hou units. When Mou Ten declined to join the competition because he deemed that arena too tiny, Ko Zen agreed and offered to find a grander battlefield for his protégée. Mou Ten declined once again saying he didn’t feel motivated to do anything with only 300 soldiers based on his achievements in the Anhou Campaign. Ko Zen then remembered that Hakurou's orders were for Mou Ten to gain some more additional years' worth of experience, and that his orders could not be disobeyed.

Sanyou Campaign Arc

When he overheard Mou Ten's goal to become a Great General of the Heavens, the old "Gramps" was overjoyed to the point of tears. However, he was quickly disappointed when Mou Ten complemented his speech, saying he was just joking and that he rather led a simple officer's life.

Ko Zen was also among those who arrived as a replacement at this time.

When Ba Tei reacted to the retreat and destruction of the unit, he decided to attack the arrogant Qin forces and almost caught up with the retreating forces of Gaku Ka, but Ko Zen, at the head of the cavalry, blocked his path and disrupted his plans.
