A jutsu developed by Rock Lee inspired by the Summer Season. It is based on when male friends see their female friends in their swimsuit, thus seeing them in a new romantic light.
At the pool over Summer 'Leeko' gets drinks for herself and 'Nejisuke'. Narrating how they have been friends for years and doesn't wish to endanger their friendship.
Asking if Nejisuke wants to go swimming, Leeko removes her shirt, creating a budding interest in Nejisuke as he sees her in her swimsuit. The two take off running down the beach before Tenten interrupts the technique.
