Background / History

Tobirama dedicated his life to Konoha. During his final retreat, he entrusted the Hokage position to Hiruzen Sarutobi and remained behind, severely wounded, to hold off pursuing enemies. Hiruzen subsequently assumed leadership during a period of internal unrest and external threats 270 349.

After returning through Reanimation Jutsu, Tobirama found a prosperous but unfamiliar ninja world. He was particularly disturbed by reports of Hiruzen’s suspected misuse of public funds and Orochimaru’s pursuit of money through violence 307 308. His later returns drew him into forced research, factory management, battles against living Konoha shinobi, and responsibility for the Senju household’s debts 352 385 427 459.

Personality

Tobirama is practical, proud, and protective of Konoha. He threatens Orochimaru if his research harms the village or the wider ninja world, and he refuses financial assistance that might damage the reputation of the Second Hokage or the Senju Clan 352 459.

His severity toward Hashirama coexists with genuine affection. Remembering the burdens his elder brother carried, Tobirama agrees to help Orochimaru so Hashirama can contact Tsunade. He later becomes exasperated when Hashirama spends his opportunities and money on games and collectibles instead 352 394.

His hostility toward Madara is both watchful and vindictive. He uses factory authority to order Madara around, bargains for a higher position after Madara retaliates, and mocks Madara’s failed ambitions and blindness. Nevertheless, he allows Madara to stay with the Senju household at Hashirama’s request, partly so he can monitor him 383 385 443 459.
