Lina is contacted by an alchemist named Diol, who had requested her help in one of his experiments. She then finds out that Diol plans to use her in creating a super chimera, which would combine her, along with a Lesser Demon and a Sea Serpent. Needless to say, Lina turns him down, despite the fact that Naga arrived... and was delighted at the aspect. Lina then had a fit and destroyed the lab, as well as electrocuting Diol and Naga.
A month later, Lina and Naga are attacked by brigands, for which Lina had dispatched two of them (and Naga) with her "Explosion Array" spell. However, when she cornered the last one, she found that Diol had found her, and he wasn't alone. He had ten confederates with him, concealed with cloaks. Diol later explained that he created his friends using a variation of the "Copy Homuculus" spell, in which he used a single strand of hair found in his wrecked lab. Thinking that Diol had created ten copies of her, Lina challenged him, knowing that the copies would be unable to use her magic. Diol then unveiled his copies... and Lina was shocked and terrified to face ten copies of Naga, for which all ten of them began laughing the original Naga's horrible laugh. Lina fainted from the horror of the spectacle.
Diol then spirited Lina way, where he was met by Vista, a brigand who had a grudge against the red-headed sorceress, and had sponsored Diol's experiments. It was later they found out that Naga was looking for Lina, and Diol sent his Naga clones to confront the sorceress. However, instead of defeating Naga, the clones bonded with her. Realizing the mistake he made, Diol ran back to Vista, where the both of them found that Naga and her clones were on their way (they could hear the laughter). In a panic, they abandoned the lab, leaving Lina - who was under the influence of a sleep spell - behind. Naga then found the sleeping sorceress, revived her, and confronted her about leaving her behind to make an alliance with Diol. Realizing there was no way to convince Naga otherwise, Lina convinced her that Diol had broke their agreement and took the money all to themselves. The two (with the clones staying behind) then caught up to Diol and Vista and captured them. Lina and Naga then collected the reward money for their capture... and wondered how in the world to deal with ten Naga clones.
