Misaka tries again. She concentrates and starts gathering water chakra within her. Simultaneously, she changes her nature to water and channels the gathered chakra to the ground. Once there, she molds it and tries to create a small source of water chakra below her feet, that she then manipulates and compresses it into a long, narrow pocket of chakra. She concentrates to compress it real hard. She then focuses even harder and uses more of her chakra to secure that the blade doesn't only go short range and fades off. Once she is ready, she performs the Tiger hand seal and then, after her foot is infused with chakra, she slams it into the ground. In an attempt to push the the pocket of chakra forward as well as turning it into actual water, she tries to release the stored chakra.
