While Sasuke and Haku fought the giant creature that had crawled up from underground, Karin and Yakumo were exploring their way toward the center of Osaka Castle.
Without the Eternal Mangekyo Sharingan, Karin had lost the ability to use Amaterasu and Susanoo. She couldn't clear a path with Amaterasu like Sasuke, so her progress lagged behind his and Haku's.
Still, their team had its own methods.

Just then, Ido, in her Spirit Body, darted through the air, letting out one soul-piercing shriek after another!
With each shriek, the demons in the street burst one after another like firecrackers, exploding into sprays of blood.
There was no doubt about it.
Ido was using the power of the Red Dragon Eye to activate a dōjutsu.
The Red Dragon Eye had been created by merging the Ketsuryūgan with the Red Eye. It had the Red Eye's ability to see through things, as well as the Ketsuryūgan's power to control blood.
Ido was now using the Red Dragon Eye's blood-manipulation ability, spreading sound waves that caused the blood in every demon blocking their path to explode.
Against powerful demons like the Upper Ranks, the Red Dragon Eye's wide-area blood explosions wouldn't have any effect. But every demon in Karin and Yakumo's way was low-ranking, so their arduous exploration had suddenly become Ido's playground.
Karin glanced at Ido, flying back and forth through the air, and regarded her with newfound wariness.
She had gone on several missions with Ido, so she was familiar with her in her Spirit Body form. But she had always thought Ido was D. Only after meeting Yakumo did she learn that D wasn't one person—or rather, that Ido was only one part of D.
Ido was already an extremely powerful being, capable of maintaining her Spirit Body
