ChЕЌun decides to join Aisha & Rinrin in their travels since KЕЌsonsan, while a noble person, isn't strong enough to unite the country and its rival factions. KЕЌsonsan is not happy hearing this since she wanted to showoff her White horse in battle. However, Rinrin arrives & helps the prisoners escape while ChЕЌun and Aisha defeat the rest of the bandits. After finding their base, ChЕЌun and Aisha fight off some of the bandits & rescue the prisoners held by them before finding themselves in a dead-end. Aisha agrees and she & Sei hide in a merchant's crate so the bandits will steal it and take it to their base. KЕЌsonsan, a local feudal lord and ChЕЌun (also known as Sei), another warrior, ask Aisha (Kan'u real name) to help to find a hidden base belonging to Bandits so they can be eliminated.
