A country that never stops crying, three orphans struggling to survive in the ruins of war - Yahiko with innocent ideals, Konan with gentleness and perseverance, and Nagato with the Eye of Destruction sleeping in his body. Their destiny was originally destined to walk with darkness until they became enemies of the world.
However, a time and space turbulence caused the Senju Tobirama who should have passed away - Konoha's second generation Hokage, master of forbidden arts, and absolute rationalist - to come as a soul. Faced with these "reincarnation eyes" that could bring disaster, Tobirama made a choice that went beyond all scripts: he concealed his identity and became the most unlikely and dangerous teacher behind these three children.
