Tezuka Phantom
From Tenipuri Info
Tezuka Phantom (手塚ファントム, Tezuka Fantomu) is a high-spin shot.
It is the inverse application of Tezuka Zone. By applying a spin to the ball six times stronger than used for Tezuka Zone[1], it forces the opponent's return out of bounds[2]. If the opponent softens the spin on the ball enough while hitting towards the middle of the court, it does not work[3].
The burden on the user's arm is immense.
