The Uchiha Clan Massacre? I’ll Turn Everyone into Cthulhu!

[Transmigrate into Naruto, sanity points plummeting!] Uchiha Kagami transmigrates on the eve of the Uchiha clan's annihilation. He obtains the Cthulhu Lord System. What? The Uchiha clan is going to be wiped out? Have you ever seen a strange ninjutsu called “Blood-Tear Bodhisattva,” which can rival the Susanoo despite using only a Three-Tomoe Sharingan? Have you ever seen a blood-red moon, an enormous pupil hanging high above the night? Have you ever seen the dead return, even though they were clearly dead? Make the bizarre real. Create the absurd. Bring forth the gods. In the end, this world will have only one and no other: the Divine Lord.
