Nany Nataresion Neinhalten, known as Nana, is a pre-pubescent magician from a parallel dimension. Her magical abilities stem from her interdimensional nature but carry significant consequences: using them triggers her transformation into an adult form and compels her return to her home dimension. This risk initially makes her reluctant to employ magic during missions.

After the Melty Lancer unit disbanded, she enrolled in school alongside fellow member Jun Kamishiro. During this period, she actively avoided magic to prevent triggering her transformation and interdimensional return.

As a member of the reactivated Melty Lancer team, she contributes her magical abilities against threats like the Defiant terrorists and the Iyonesco conspiracy. Her interdimensional origin and powers become relevant within the broader narrative involving genetic experiments and endangered species.
