A genius with an IQ of 999. She has escaped from a research facility that gathers children with special abilities and has retreated into a hyperdimensional space to hide from her pursuers. The cube hanging from her neck occasionally glows blue-white and emits energy, charging all her electrical appliances so she doesn't have to charge her phone. She likes cats, games, and sweets, and her name Henya comes from the Spanish word Genia (genius), but even with an IQ of 999, she can't remember how to spell it, so she tells everyone "Henya" as she hears it.
