Neku Sakuraba is a talented fighter but he’s completely outmatched here. Tatsumaki could create a barrier around Neku and just blow him up from inside or just launch a single attack that destroys him. Neku has nowhere to hide and none of his attacks would be capable of breaching Tatsumaki’s ultimate defense. It is pretty much indestructible and Neku would need a whole sequel of power ups to even begin to challenge her abilities. Right now it doesn’t seem likely that he could ever manage a comeback. Tatsumaki wins.
