Mama
Yukiko’s Kekkai Genkai can be used in a deviant way, using the same principle of « giving life » to an inanimate thing, passing the chakra through the roots from several points of energy in the body. It is called « Futabi Tatsu » (再び立つ) = « stand again » (cf Nakamura clan info pt2). It could be compared to « Edo Tensei ». It seems like a great alternative to it, because the toll isn’t human lives, but plants and animals. All the energy transfer is done through the ground and roots, using the thorns as pipes transferring energy. It allows the reconstruction of the flesh and brain, but we can’t really say the « soul » is back in. The resurrected people are mostly empty shells, with no will to live, and depending on the person who brought them back, like an infant to their mother, unable to express their suffering. They don’t seem to have any memories of their past lives, just some reflexes. Hava discovered some of the limits of Futabi Tatsu when Yukiko failed to bring back her still born baby. « I can bring back those who once breathed. But your son never did.» Hava will manipulate Yuki into bringing back her mother, Hikari, in order to test her ability to use this technique. She made her believe people lied about her suicide and Yuki could still « save her » as she had been imprisoned. So she led Yuki to perform the ritual, « to set her free». Yukiko wanted to believe so hard she could bring her family back together, she clang to this hope. She triggered her memory to write in the contract, with her own blood, writing « 母 » Mother on her belly and then on the tree used as a receptacle «子 » Child. It was long and painful, the thorns drained a lot of chakra out of Yukiko, she lost a lot of blood, giving some of her own to this « child ». After more than an hour she « raised » again, crawling, unable to stand on her trembling legs. She looked at Yukiko, muttering some indistinct words getting out painfully of her jaw until one word could be distinctive : « Mama ».
