Grimm got back to Peranos' laboratory seven days later.
"The Bloodlust Puppet?" Grimm listened attentively to Peranos who was introducing the new sorcery.
The Puppet reminded Grimm of the students back on the ship who could pull strings to control a puppet and kill.
In retrospect, Grimm believed that the reason that student got killed without an apparent reason was probably that some student in the group desired the magical tool which could conjure up the puppet. The incident caused a stir back then since the puppet girl was known for her ruthless character.
