The name of mysterious dark-clothed man is Ryuori Tenketsu and he is Culexworm. On the previous last scene, Jiiya had been defeated by Ryouri Tenketsu. His motive is to close down and bankrupt all the restaurant, either give other chef lost confident about their own cooking or steal the heart of their own customers. Riku Kagami hired him as a chef to cook all cuisine in one of the ZECT party. Now Tendou challenge him to a cook-off in the Dark Kitchen Competition. Then he visit Jiiya at the hospital and Jiiya tell Tendou that he has twins' younger brother with a legendary white kitchen knife, after that Tendou seeks Jiiya's twin brother. But can Tendou out-cook the "Dark Chef" that once defeated himself?

On the last scene previous episode, Kagami (Gattack) try to defend Tsurugi (Scorpioworm) from Tendou (Kabuto) from destroying Tsurugi (while Tendou don't know why Kagami do that, only Kagami know who is the Scorpioworm) and they have a fight. Then with the help of Hyper Kabuto all things are settled, nobody is hurt or die. In this episode lies all the complexity, unaswered and confiusing questions. A recent shot of Tendou's parents were shown, and they are in fact the same parents as in Hiyori's picture, which leads us to the conclusion that Hiyori may indeed be Tendou's real sister. Did Rena Mamiya, Mishima & ZECT really know the existence of Hyper Zecter & Hyper Kabuto? Now Kagami and Tendou is really shocked that Hiyori can turn into 'Sisyraworm' WORM sort-of-butterfly!
