Reborn as Eren Yeager: The Gacha System

Chapter 101: The Map of Old Wounds

Armin’s research took a new, deliberate shape over the following month — no longer a scramble against a countdown, but the patient, methodical work of a scholar finally given time to do the job properly.

"I’ve cross-referenced every major Titan engagement of the war," he said, unrolling a hand-drawn map across the war council table, now dusty from years of disuse but pressed back into service. "Every transformation, every battle where Coordinate power was used at scale. I marked them all."

The map bore fourteen small red circles, scattered from Shiganshina’s original battlegrounds all the way to the distant coastline where the Anchorless entity had once surfaced.

"Fourteen possible sites," Mikasa said, studying the spread. "Fourteen places where a child like Tobias could theoretically be born."

"Possible, not certain," Armin cautioned. "Tobias himself said the wounds are small, mostly dormant. Most of these sites probably produced nothing at all. But if even a handful did—"

"Then there could be more children out there right now, alone, frightened, not understanding what’s speaking through them," Ymir finished, arms crossed, old memory of her own frightening isolation clearly coloring her urgency. "We don’t have the luxury of treating this like an academic exercise."

[Mission "Echoes of the War" — Sub-objective generated: Survey identified sites for anomaly activity. Estimated time required: 6-14 months, depending on team size and resource allocation.]

"Months," Eren said, reading the projection. "That’s a long search."

"It’s an honest one," Mikasa said. "Better than rushing and missing a child who needs exactly the kind of care Tobias is getting now."

They divided the search carefully, deliberately, learning from every mistake the original countdown had once forced upon them — no single point of failure, no one person carrying the entire weight alone.

Reiner and Annie took the northern sites, closest to the old Marleyan coastline, their combined knowledge of Titan-scale combat useful for assessing residual resonance patterns Historia’s people had taught them to recognize. Armin and Historia handled the scholarly work, correlating findings against the old Aeldrin texts. Zeke, given careful trust after years of proven commitment, took responsibility for the sites nearest his own old battlefields, working alongside a small Garrison escort still cautious around him but no longer openly hostile.

Eren and Mikasa took the sites closest to home — the cliffs where Zeke’s confrontation had nearly ended both their lives, the basin where Ymir’s binding had taken place, each visit carrying its own particular weight of memory.

"It’s strange, coming back here," Mikasa said, standing at the cliff’s edge where she’d once climbed a rope to save Eren’s transformed arm from an entity’s grip. "Everything looks so ordinary now. Grass growing back over the scarred ground. Birds nesting where a Titan once fell."

"The land heals," Eren said, testing the strange, dormant resonance Tobias had taught them to sense, a careful stillness in the mind rather than any physical instrument. "Slower than people do, maybe. But it heals."

[Site survey: Cliffs — Resonance detected: Minimal. Classification: Dormant, non-viable for anomaly formation. No further action required.]

"Nothing here," Eren said, relief evident in his voice. "Whatever happened during Zeke’s and my fight, it didn’t leave the kind of wound Tobias described."

They moved through three more sites over the following weeks, each survey a strange blend of old grief and quiet, careful hope — standing in places that had once nearly ended everything, now simply grass and wind and the patient work of time.

The fifth site changed everything.

"This is where the original wall breach happened," Mikasa said quietly, standing amid the rebuilt southern district of Shiganshina, the scar of Bertholt’s colossal transformation long since paved over with new streets and rebuilt homes. "If there’s resonance anywhere, it would be here."

Eren closed his eyes, reaching for the careful stillness Tobias’s fragmented guidance had taught him, and felt, immediately, something far stronger than anything the previous sites had shown.

[Site survey: Original Shiganshina breach point — Resonance detected: SIGNIFICANT. Classification: Active. Immediate investigation recommended.]

"There’s something here," he said, opening his eyes, dread building steady in his chest. "Strong. Stronger than what we felt with Tobias."

They found the source three streets over — a modest bakery, run by a young couple who’d settled in Shiganshina only two years prior, their infant daughter sleeping peacefully in a cradle behind the counter.

"She’s perfectly healthy," the mother said, confused by the careful, gentle questions Historia posed about the child’s behavior. "Sleeps well, eats well, laughs all the time. Why do you ask?"

Eren studied the sleeping infant, no more than eight months old, and felt the resonance radiating from her small, peaceful form, quieter than Tobias’s but unmistakably present.

[Anomaly confirmed: Infant, unnamed condition presenting as latent rather than active. Recommend gentle, long-term monitoring rather than immediate intervention. Threat level: None currently.]

"She’s not like Tobias," Historia said quietly, once they’d stepped outside, careful not to alarm the young parents further than the vague explanation they’d offered about "routine post-war health surveys." "The resonance in her is dormant. Sleeping, the way Tobias’s was, probably, until something disturbed it."

"Then we watch," Mikasa said. "Carefully. We don’t tell the parents everything yet — not until we understand more about what we’re actually dealing with. But we make sure someone’s paying attention, in case it ever wakes."

That evening, back home, Eren found Carla sitting with Tobias in the garden, the two children — one carrying ancient fragments, one utterly ordinary — playing some invented game among the pale, hardy flowers with the easy, uncomplicated friendship only children seemed capable of forming despite circumstances neither fully understood.

"They get along well," Mikasa said, watching from the doorway.

"Carla doesn’t see him as strange," Eren said. "Just as her friend who sometimes talks in an old voice and sometimes doesn’t. I think that’s exactly the kind of care he actually needs."

[Mission "Echoes of the War" — Progress: 2/14 sites confirmed active or resonant. Estimated completion: 5-13 months remaining.]

"A long search," Mikasa said, watching the children’s careful, uncomplicated joy. "But maybe that’s exactly right. Slow enough that nobody gets rushed into a countdown again. Careful enough that every child we find gets exactly the kind of patient understanding Tobias is getting now."

Eren pulled her close, watching Carla laugh at something Tobias said in his ordinary child’s voice, the ancient weight momentarily, blessedly quiet beneath simple, present joy.

"Fourteen sites," he said. "However many children we find. We do this properly this time. No forced urgency. No manipulation. Just patient, honest care."

"Just that," Mikasa agreed, and the garden settled into warm evening quiet around them, two children playing among flowers that bloomed every year despite the harshest winters, carrying forward, in their own small way, everything the past had cost and everything the future still hoped to properly heal.
