Raku

The ghost of a cat that Yuzu Kurosaki once fed is known as Raku. The cat Raku has long ears and whiskers, short blonde fur, and a white underbelly. Its eyes are a vivid green that resembles emeralds. Raku may not have had nine lives because, like Happy, he tragically lost one after being hit by a car, but being a ghost has its benefits.

When Hollows threaten to eat the soul of his human, Yuzu, he can transform into a spirit and take the form of a lion with a blazing mane. Raku can surround himself with fire when in this form and has amazing power and speed. It can easily defeat a Huge Hollow on its own, demonstrating that its strength is comparable to that of a ranking Shinigami officer.

They have no chance against this morphing attack, known as the Karakura Lion Jet for the incredible speed and power it unleashes along with its flames. In this form, Raku can even take on a Hollow who is three times his size. This is made possible by his strong reiatsu, or spiritual force.
