A fan-created widely-known [[genderswap|male version]] of [[Nagato Yuki]]. Unlike Yuki, who only wears her glasses when reading, he still wears his glasses most of the time. Other than that, he still retains her personality and traits.

Phonetically, the genderswapped version's name is virtually the same as the original, it only takes the lengthening of the "yu" sound.
