Onmyou Taisenki - Season 1 Episode 23 White Tiger Disappears

Riku has been having a lot of dreams lately, each involving a pleasant yet sad woman. When the giant Kimon in the Mikazuchi building opens, a lot of Youkai run amuck. Although Mikazuchi closes the Kimon with ease, there are still some Youkai out there. So, Nazuna uses Toujinfu to gather the remaining Youkai, and then Souma and Fusanoshin finish them off. At night, Yuuma and Rangetsu return and fight Riku and Kogenta. Kogenta is winning the battle, but Riku seems to be in a daze.
