Matryoshka LT are empowered vessels used to give birth to Star Children through the several types of Classmating. They are found in Labyrinths, and are consumed when giving birth to a Star Child (although twins will only consume one Matryoshka LT). Like all types of Matryoshka, they cannot be sold or bought. Matryoshka LT will cause any newborn Star Child(ren) born with it to have the Ether element, regardless of the Star Child's mother. As the Ether Element cannot be given to Star Children through regular Classmating with Heroines, the Matryoshka LT is possibly the most valuable Matryoshka.
