Chapter 143: Two and a Half Years

Naruto did not shout inside Iruka's apartment. He waited until the photograph was safely on the table, thanked Iruka for answering, and marched the twins outside. Chōji followed while finishing the last of his snacks.

"You knew from the beginning," Naruto said on the landing.

"You never asked us directly," Tenyu replied.

"We helped you find the answer," Maki added.

"You let me read that entire terrible book."

"You learned to recruit a team."

Naruto chased them down the street. The pursuit remained a game until one monitoring seal reported that they had left the approved route. Ayame's woven sparrow intercepted the group before the market and guided everyone back to Ichiraku. No one was struck.

The twins lost unsupervised route privileges for a week because they had treated monitoring boundaries as optional. They wrote Naruto an apology for withholding information to extend the game, then worked beside him preparing vegetables for the evening service. Naruto apologized for planning revenge before asking why they had continued.

"People kept joining you," Tenyu said.

"You were happy," Maki said.

Naruto remained angry and understood them at the same time. Chōji's idea had succeeded. Shikamaru had spoken to him without disgust. Shino had remembered his request. For one afternoon, finding an answer had mattered more than what the village whispered about him.

Tonbo returned from his follow-up trip to Gale Valley and received a family review of every decision. He explained that playful concealment stopped being harmless when it made someone spend time, accept risk, or cross boundaries without informed choice. Then Naruto presented him with an aggressively bitter ration bar as repayment for Eightfold Flavor.

Tonbo ate it without using genjutsu and asked for the recipe. Naruto did not visit for six days. Konoha settled into new routines.

The three captured mercenaries were tried under the mission agreements governing attacks within the Land of Fire. Their testimony identified Gatō's intermediary but not a signed order from Gatō himself. Konoha issued warrants, froze reachable assets, and shared evidence with the daimyō's court. The shipping magnate lost routes and agents without offering a target Tonbo could lawfully assassinate.

Some Hagoromo survivors wanted immediate retaliation. Others wanted nothing connected to shinobi again. Kento used external accounts to support funerals, treatment, and temporary housing before rebuilding any company. The order of spending became his first answer to the classism Tonbo had observed when they met.

Hagoromo survivors arrived in small groups from underground exits, distant offices, and trade stations. Hiruzen offered guarded district housing, access to mission work, and representation in negotiations over property. Kento accepted integration only after the clan council—reduced but not erased—approved it. Their companies remained legally distinct where possible. Their children entered Konoha classes without surrendering Gale Valley traditions.

The choice strengthened Konoha and saved the clan from dependence upon isolated estates. It also created resentment among survivors who believed protection had become recruitment. Tonbo recorded both outcomes rather than calling the arrangement purely generous. Two and a half years passed.

Naruto's class reached its third Academy year. Kiba and Sasuke dominated formal marks, though in different ways. Kiba treated every subject as preparation for the office he still intended to claim. Sasuke pursued competence with the intensity of someone measuring himself against an older brother. Naruto improved rapidly in practical exercises and remained poor at patient theory, but he no longer treated asking for help as surrender.

Chōji never accepted the permanent title of strategist. Naruto continued using it whenever a problem involved food or photographs. Shino occasionally assisted when his colonies allowed. Shikamaru refused every formal appointment while providing answers often enough to undermine the refusal.

Tenyu and Maki grew old enough to attend structured preparatory lessons. Ayame and Tonbo maintained monitoring as an explained family rule, reducing its reach as their judgment improved. The twins could travel approved routes together, carry emergency seals, and appeal consequences to both parents. Neither freedom nor supervision remained fixed merely because an earlier system had worked.

Ayame expanded Ichiraku's staff with Tōsei and Teuchi rather than assuming the children would inherit it. New apprentices learned recipes, purchasing, sanitation, and service. A second preparation kitchen supplied mission rations without changing the small counter that regular customers considered home. Family money supported Tonbo's research; research success never converted Ayame's work into background scenery.

Tonbo divided the years among family, Analysis Team command, Yakumo's continuing care, Sealed Horizon, and Atmospheric Guidance.

Gale Valley measurements led him beyond producing local rain. The mature form mapped pressure, heat, moisture, terrain, and existing current into a temporary network. Yin Release distorted how air responded at selected leverage points; ordinary physics amplified the initial guidance. The technique did not create weather from nothing and could not ignore stable conditions. He named the completed battlefield form Atmospheric Guidance: Tempest Field.

Testing occurred on an uninhabited basin with evacuation barriers, external observers, and a cancellation array. Tonbo planted anchor seals across the terrain and spent several seconds establishing gradients. Wind rose from flat ground. Dust marked crossing currents. Narrow rotations became columns, then a connected field that lifted stone and tore shallow trenches through soil.

The observers included a barrier specialist, a medic, an Analysis Team recorder, and Hagoromo Ki. Ki compared the artificial currents with Gale Valley and rejected the first description of them as identical. Tonbo's field lacked the valley's deep seasonal layers and recovered more quickly after disruption. The correction reduced the technique's predicted reach and improved its cancellation plan.

Tonbo held the weakest operational form for forty seconds before ending it.

The basin continued moving after he stopped. That delay became the first limitation in the manual: termination of chakra did not immediately cancel natural momentum. Allies required shelter and advance warning. Civilians could not remain anywhere inside the modeled debris zone.

At full theoretical scale, Tempest Field required chakra beyond Tonbo's reserves. Linked storage arrays could supply part of it. Voluntary external contributors might supply more. No battlefield model treated a jinchūriki or teammate as an object available on demand.

The technique excelled against very large targets and armies that could not simply leave the affected region. It was inefficient against a single fast shinobi. Space–time ninjutsu, sealed shelters, terrain disruption, or killing the anchors during setup could defeat it. Tonbo wrote those failures into the same document as its strengths.

"The strongest technique you have made?" Ayame asked after reading the public-safe summary.

"The largest. Not the strongest in every situation."

"And the safest?"

"No. Sealed Horizon is safer because its purpose is shelter."

She made him say the distinction to Tenyu and Maki. The twins had seen the distant dust columns from behind the observation barrier and wanted to learn immediately.

"You begin with measuring wind in the yard," Tonbo told them.

"For two and a half years?" Maki asked.

"Longer, if you ignore the instruments."

The completed technique did not end research. It converted a dangerous idea into a documented system of uses, failures, and responsibilities.

Tonbo archived the full method behind contribution and safety requirements rather than keeping it solely as a family secret. No student would receive the large-scale form before demonstrating weather theory, barrier control, evacuation planning, and the willingness to cancel a successful test. Power without an end condition was an accident awaiting confidence.

That autumn, while Konoha prepared its third-year students for night training, another long-delayed crisis reached its decision.
