The name of an animated film, several people are called Red Dog, and several people are fighting against the dark forces. I only remember 99 stitches.

This animation is called Invincible in the World-Super Ninja. Japanese Translation of The Crow and the Dog

The protagonist is Black Hawk, the 32nd generation head of the Tiangou Sect. His sword is called dragonfly, and people call it "Dragonfly Demon Sword". Killing people never has blood (sucking dry). If you don't suck the blood of others, you will suck the blood of your master. The most powerful killing skill is "near, soldier, fighter, full array, column, middle, front-nine array", which is BT, and can be started when one episode falls asleep. He has four protectors under his command, namely North Xuanwu-Red Tengu, West White Tiger, East Qinglong and South Suzaku. Qinglong is a child, using a gyro. Suzaku is a woman, using "99 stitches". Xuanwu is a red tengu (Japanese tengu is a monster with a red nose). It was originally made of mace, but it was later destroyed by the devil. So it went with the Black Hawk and his party to find the legendary weapon, and later subdued it and called it "Lei Feng's stick" (goldfish changed). "Lei Feng" has the ability to manipulate the wind. The white tiger originally used a double-edged sword with ten thousand words (ten thousand), but it was also destroyed by the demon king. He also went to look for the legendary weapon with the Black Hawk and his party, and later surrendered the demon knife (changed from whitebait) called "Beating Dragon's Teeth". It is said that "beating the dragon's teeth" can cut off anything, and there is a dragon in the knife. Four guardians can launch an enchantment together, which is called "four-door blocking array". It is very powerful, but it is broken (sweat). The sword of the enemy demon king, made together with "Dragon's Tooth", is called "Female Beast". There are four women-like monsters on the knife, which can be attached to a person to manipulate that person. He also has a drifting castle. The ghost gate in the north of the castle can summon monsters, which is very BT. Later, in order to deal with the lich king, the Black Hawk let Qinglong find the warship left by the dragon-"Dragon Ship (Spacecraft)" ...

The comic version is called "crow dog", the protagonist is called Dou, and the demon knife is called.
