After completing the eye transplant, Shinji carefully examined the removed Mangekyō. The two eyeballs gleamed with vivid vitality, utterly different from before.
"Not only had they regained their light, it seemed their Dojutsu had been fully replenished as well."
After musing to himself, he carefully placed the pair of Mangekyō into a specially made nutrient container.

His vacation days were busy but fulfilling.
Seeing Shinji throw himself wholeheartedly into Medical Ninjutsu, Kaoru Kusa thought something
