It reminds me of a cross between Spider-man and Freaky Friday. Juzo is an assassin the it bit by a wasp. Unlike in Spider-man instead of giving him superpowers it changes him back into a teenager. He must then go to school and deal with all the awkwardness that comes with being a teen. Geared towards older teens and action packed.

Top assassin turned… middle schooler? Juzo Ogami is stung by a genetically manipulated wasp during a job and regresses to the age of twelve - now he’s scoping out the school his boss’ daughter is supposed to attend and determine if it is safe. As it turns out Ogami, who never made it past elementary school, loves learning and throws himself into his new life. But can he continue to balance life as a middle schooler with his job as an assassin? And can he keep his new friends safe without them discovering the truth? Shonen fans are sure to love this (relatively) new series.
