Ch. 143Dojutsu: Unlimited Blade Works?
Menma subjected Shin Uchiha to Hashirama cell fusion and a brutal Sharingan transplant, helping him awaken the Mangekyō Sharingan and then stabilize it with a new seed and a sealing technique. Shin revealed that his altered Mangekyō Dojutsu could store non-living objects in an alternate space and create near-identical clones of objects he marked.
- Menma injected Shin Uchiha with Hashirama Cells Fusion Fluid and transplanted dozens of Sharingan into his body.
- Menma carved holes into Shin Uchiha's skull and implanted additional Sharingan, then urged him to control their ocular power.
- Shin Uchiha drew the ocular power into his eyes and awakened the Mangekyō Sharingan, but his Chakra quickly began to run out.
- Menma fed Shin Uchiha a new variety of seed and sealed his body with the Modified Four Symbols Sealing Technique, allowing the Mangekyō to remain supplied with power.
- Shin Uchiha described his left-eye alternate space and his right-eye ability to mark objects and create near-identical clones, surprising Menma.
