Tiger Wand was born after Kaori came back from the dead, so his real mother is the Suture Woman, also known as Brain Blossom. The suture woman is undoubtedly the "she" mentioned by Tiger Cane Yosuke, and her current relationship with Tiger Cane Yohito is that of husband and wife, for example, but what's more interesting is the "Kaori" mentioned by Tiger Cane Yosuke. This "dead" woman is the Suture woman who appeared in front of Tigress' father and son. Kaori had no children with Tigress Hitoshi before she died, so Tigress Yohito is supposed to be Tigress Hitoshi's child with the Suture woman, and Tigress Umisuke knows that the Suture woman is very dangerous. There is another single teenager in the story who is also likely to be Brainflower's child: Junpei Yoshino, who is also mentioned by Brainflower in 136 words. If this is true, then Brainflower, who switched bodies to have a child with the jutsu gene and then had the child kill each other, is definitely the number one "netherworlder" of the Spellbound War.
