Lillia and Treize

At the start of Lillia's summer vacation, Treize arrives after traveling from Ikstova for twenty days by motorbike and brings her back home. That night, Allison informs her daughter that instead of mother and daughter going on a trip to Lartika, Lillia would now be going with Treize, though Lillia is initially reluctant about the change in plans. After arriving in Lartika, the two discover they will be staying in an expensive hotel due to Treize being a member of the royal Ikstova family. Lillia and Treize go into town, but quickly get lost despite having a map handy. A young boy approaches them and suggests they hire him to guide them around town and back to their hotel, which they agree upon. Once back to the hotel, though, a policeman intervenes and says that paying the boy for his services is prohibited by town law. The next day, Lillia and Treize take a ride on a sight-seeing plane flown by a retired military pilot. At that time, Travas informs Allison how an evil plan against Treize and his twin sister is brewing.
