Field Surgery

Haru quickly passed through the gates of Konoha. He needed to get back to Kirigakure ASAP. If he didn't, he didn't know what would happen to Altar.

As he reached the wooded area of Konohagakure, out of sight, he assesed the situation, and decided it would be best to implant the sharingan first, so that he could move at his full speed without fear of destroying it. Quickly, Haru removed the sharingan from where he had stored it, placing a hand on his face and using the optic splitting technique he had created to replicate his nerves, focusing them to a point in his forehead, and creating a new slit for an eye, an inch or two to the right of his Yin seal. He would implant the eye via the mystical palm technique, hastily wrapping his head in bandages. That would do for now. 

Now, Haru turned his sights to home; he would be in Kirigakure very soon.
