* Regular Edition
* Limited Edition

**Mazeru na Kiken** (混ぜるな危険, *Don't Mix Up With Danger*) is the first opening theme of the anime *Ushio and Tora*, performed by Kinniku Shojo Tai (also known as KING-SHOW). The song is composed by Honjo Toshiaki while the lyrics are by Kenji Ohtsuki.

## Opening Animation

The opening begins on a background of lightning before quickly transitioning to the Beast Spear, to Tora's claws, to a close-up of Ushio's eyes while wielding the Beast Spear, and then to Tora's eyes growing larger. As the initial lyrics are sung, the words are written on screen in different colours on top of a black background while shaking vigorously. The last line of the first verse scrolls downward in between a smiling Ushio and Tora.

Scenery of the moon is displayed with dark clouds surfacing by, while the logo appears on screen. After a few seconds, the logo explodes into red petals when Ushio and Tora jump into the sky.

Ushio is seen happily walking in his school uniform along with Asako and Mayuko until he angrily turns around to face a menacing Tora. Tension between the two is portrayed with their faces overlaid with speed-lines and being separated by two currents of red lightning flowing in between.

The scene shifts to Kagari holding Raishin from behind, as she holds out her hand in front of him to extend her blade. Next, Hyo holds up a seal which covers his left eye and reveals his other eye glowing blue. Omamori-sama walks across a bridge with cherry blossom trees in the foreground. Several of the Eastern yokai such as Hitotsuki, Yamanmoto, Izuna, Ibuki, and Kappa are seen in a dark area as clouds cover them to make them appear as silhouettes. Multiple red eyes then glow through the clouds.

Up next is the Kohamei Sect with Oyakume-sama in the background. Silhouettes of the four successors of the Beast Spear (Kirio, Hinowa, Satoru, Nagare) are in front of her. It focuses on Shigure who appears in front of them and brighter than the rest, before transitioning to his wife, Sumako. Sumako is shown sitting while holding the barrier, with Hakumen no Mono's eye behind her. Jie Mei also floats around her in a circle.

The scene from Episode 1 appears, with Tora smiling evilly and Ushio grabbing the Beast Spear to transform for the first time. It transitions to him running across Fusuma and attacking his tentacles along with Tora using lightning.

In the next scene, Ushio is shirtless and shown slicing with the Beast Spear. Tora is shown after biting a yokai and causing blood to gush out. The two jump to the ground and fire explodes behind them. They smile at each other happily while surrounded by several yokai and a sea of fire. Before ending, the camera switches its focus on either Ushio or Tora. Tora's claw marks appear twice and then the opening ends with the two jumping in the air in front of an orange background with flames around them.

### Updated Version

Starting from Episode 14 and afterwards, the opening replaces a few scenes with some new ones. Kagari and Raishin, Hyo, Omamori-sama, the Eastern Yokai, and Fusuma's scenes were removed.

Inasa is shown sitting in a chair with many yokai experiments and Kirlian Scythes on the ground. It switches to the H.A.M.M.R. Institute in their lab with a red "23" in the background behind them. Izuna circles around the screen before it switches to Giryo welding the Beast Spear with rage.

A hand with sharp claws grabs the spear, which is revealed to be Ushio after fully transforming into a beast. It zooms into Ushio's crystalline eye and transitions to the Kohamei Sect. Instead of being silhouettes, the Oyakume and four Beast Spear successors are now shown brightly.

After the scene from Episode 1 that was in the original opening, there's a new scene with Ushio riding atop Tora in a moonlit background. Towako attacks Ushio, and he dodges all the projectiles before the two clash. Tora runs across the wall while dodging the attacks from Hakumen Metamorphose and then blows it up with a burst of fire from his mouth.
