The pursuit found them on the fifth day, in a valley where the rice paddies gave way to bamboo groves that whispered secrets to each other. Ren heard them coming before he saw them — the Watch guardian's thousand eyes, brushing against his awareness like insect legs.
Four, Kai noted, crouched on a branch that shouldn't have held his weight. Two red. One silver. One green.
"Attack, Watch, Repair," Ren translated, automatic. "No Defense."
Mistake, Kai said, delighted. They think you're 0★. They think you need no blocking. They think...
"They think wrong."
Ren didn't run. Running was what 0★ did — what failures did, what the defined did when confronted by their betters. He walked into the grove's center, where the bamboo opened into a natural arena, and he let his white hair catch the afternoon light, and he let his shoulders straighten to their full six feet two inches, and he waited.
The Church squad emerged from four directions, closing the trap they'd spent five days preparing.
First: the two Attack guardians. Twins in the way of all 1★ Attack — simple, violent, obedient. Their manifestations were hounds of compressed flame, red fur smoking, teeth that burned rather than cut. The brothers who hosted them were young, eager, already grinning at the easy hunt.
Second: the Repair guardian. A vessel — ceramic, gentle, shaped like a teapot with arms. Its host was older, tired, carrying bandages and poultices for after the capture. Not a fighter. A cleaner.
Third: the Watch guardian. And this one — this one was different.
It manifested as a single eye, human-sized, floating where its host's head should be. The host itself was invisible, or merged, or sacrificed. The eye turned toward Ren, and Ren felt it see him — not his body, not his white hair, not his wooden sword, but the silver behind his ribs, the undefined presence that made him more than 0★.
The eye turned toward Kai.
And screamed.
The sound wasn't audible. It was perceptual — a thousand sensory channels overloading at once, the Watch guardian trying to process what could not be processed, trying to classify what refused classification. The eye bled silver tears, then clear ones, then nothing at all, and the host — the invisible host — became visible as they collapsed, a young woman convulsing, her own eyes rolled back, seeing too much.
"What—" one Attack twin started.
Fun! Kai declared, and threw a pebble.
---
The battle that followed wasn't a battle. It was play, and that made it worse for the Church guardians.
Ren moved first — not toward the twins, but toward the Repair host. She was raising her ceramic vessel, trying to create distance, trying to heal the collapsed Watch guardian before anything else happened.
"Sorry," Ren said, and struck her temple with Miso's knife — flat side, not edge, enough to stun, not kill. The ceramic vessel cracked, spilling healing water that became steam, became confusion.
One Attack twin lunged. Flame-hound manifesting fully, burning bamboo, turning the arena to smoke and ash. Ren didn't dodge — Kai replaced him, silver body flickering between states, and the hound's teeth closed on nothing that became pebble that became bird that flew through the twin's hair, cawing laughter.
Tag, Kai whispered, appearing behind the twin. You're it.
The twin spun, flame-hound trailing burning air, and Ren — real Ren, not replaced, just moved — struck his knee with the wooden sword. Not enough to break. Enough to embarrass. The twin fell, cursing, his guardian's flames scorching his own robes.
The second twin was smarter. He hung back, assessing, his hound low and circling. He'd seen the Watch guardian collapse, seen his brother humiliated, seen the 0★ boy move with training that shouldn't exist.
"You're not empty," he said. Not accusing. Understanding, too late.
"No," Ren agreed. "I'm undefined."
Kai laughed, and the laugh was gravity, was direction, was the bamboo grove leaning toward the sound, the twin's hound stumbling, falling upward for three impossible seconds before crashing down.
Boring, Kai declared. You define. You limit. You wait for permission. We don't wait. We play.
The second twin tried to run. Ren let him — three steps, four, enough to think escape possible — then threw Miso's knife. Not at the twin. At the bamboo stalk ahead of him. The stalk negotiated with Kai's presence and became spear, became wall, became laughter that knocked the twin unconscious without touching him.
Silence, except for the Watch guardian's host, still convulsing, still seeing.
Ren walked to her. Knelt. Pressed his hands to her temples — the way Sister Yuki had taught him, basic stabilization, human skill without guardian aid.
"Stop looking," he whispered. "Stop trying to see. He's not... he's not something you can perceive. Close your eyes. Breathe."
The convulsions slowed. The woman's eyes — her own, brown, frightened — focused on him.
"What..." she managed. "What is he?"
Ren considered the question. Kai crouched beside him, silver and curious, faceless head tilted at the woman who had almost seen him.
"Undefined," Ren said finally. "The sixth. The..."
He looked at Kai. Kai threw a pebble that became a star that became encouragement.
"...the fun," Ren finished, smiling despite himself. "Tell them. Tell the Church. Tell the Definer. We're not hiding anymore. We're not 0★. We're not anything they have words for. And if they keep hunting us, we'll keep playing. And their guardians will keep..." He gestured at her collapsed form, at the cracked ceramic, at the burned twins. "...breaking."
The woman understood. He could see it — the fear, yes, but also the relief. She'd been sent to capture a failure. She'd found something else. Something that didn't fit the theology, the system, the four stars that held the world together.
"Go," Ren said. He pressed Miso's copper coins into her hand — more than she'd need for the journey back. "Heal them. Heal yourself. Tell them what you saw. Tell them... tell them the naming failed."
She went. Carrying her unconscious comrades, one over each shoulder, the cracked ceramic vessel leaking healing water that became questions with every step.
Ren watched them go. Kai watched Ren.
That was... Kai searched for the word. Serious?
"Necessary," Ren said. He was shaking now, adrenaline fading, the cost of visible becoming apparent. "We needed them to stop. We needed... we needed the Church to know that hunting us costs more than ignoring us."
And? Kai pressed. The fun?
Ren looked at his hands. They were steady. They were always steady. But now they were steady with choice, not training — with the memory of throwing a knife that became a wall, of moving through battle like play, of being seen and surviving it.
"The fun was there," he admitted. "When you replaced me. When the hound bit nothing. That was... that was good."
Good, Kai repeated, tasting it. Different from fun. But okay. Good is... sustainable?
"I don't know. Let's find out."
They walked on, toward Kurogane's smoke, toward the Dominion where stars were weapons and undefined was impossible. Behind them, the Church squad carried their broken guardians and their broken certainty back to Sakura.
Ahead, the Definer waited — not yet, not directly, but aware now, preparing, learning to name what refused naming.
But that was weeks away. Today, they had played, and won, and the bamboo grove whispered their names in a language that didn't exist yet.
That was enough.
