Extra / bonus chapter
The Sistermon Blanc's information pane materialized in Luke's awareness.
「 Sistermon Blanc 」 Race: Digimon (Doll-type) Quality: Collectible Level: ★★★ (Three-Star, Rookie) Skills: Divine Judgment Pierce, Defense Wave, Sister Cross, Awakening
Divine Judgment Pierce: Trident-based piercing strike infused with Light-element energy and penetration properties. Damage is doubled against opponents bearing Dark-element attributes.
Defense Wave: User drives the trident into the ground and channels a barrier wave outward from the impact. Especially effective against ranged attacks.
Sister Cross: The signature combination technique of the Sistermon line. When activated, the user projects partial echoes of Sistermon Noir and Sistermon Ciel into the battlefield. A full-power coordinated strike produces destructive output comparable to a Champion-level Digimon.
Awakening: Activates the Holy Brand, entering an empowered state. Level increases by one tier for the duration.
"The mana backflow from a Three-Star card isn't enough to push my realm anymore," Luke observed.
The Sistermon Blanc was a Rookie-level Digimon at Three-Star Collectible quality. By the Magic Card Civilization's tier classification, that was a high-quality entry-tier card. It satisfied Phase One's passing requirement comfortably, with significant margin.
He'd designed it deliberately at Rookie level. The Simulation Construction process had given him a reasonably accurate prediction of the card's final form before he'd even started crafting, and he'd known going in that he was building toward a Rookie-tier outcome.
Crafting Sistermon directly at Champion level would have produced a mid-tier card with combat capabilities approaching upper-tier brackets. Several of his planned material choices would have supported that, and the Digital World worldview integration was strong enough to anchor a higher-initial-tier construction without trouble.
He hadn't done that, because Digimon's defining trait wasn't raw power. It was evolution. Specifically, Network Evolution, the multi-path flexibility that allowed a Digimon to adapt its evolution route to whatever environmental conditions or tactical needs emerged in real time. Starting Sistermon at Champion tier would have collapsed the available evolution paths upward, narrowing her future flexibility for the sake of higher initial power.
That trade wasn't worth it. The Sistermon line's value proposition was the network, not the starting point.
Rookie tier preserved maximum future flexibility. Multiple Champion-tier paths. Multiple Ultimate-tier paths beyond those. Eventually, a Mega-tier ceiling that depended on which earlier path she'd taken.
Building at Rookie was the correct strategic decision. The lower initial power was a price he was willing to pay for evolutionary breadth.
"The Sister Cross output is higher than I expected, though." Luke reread the skill description. "A Rookie-tier user producing Champion-tier damage output through a coordinated combination technique. That's already pushing into upper-tier territory."
The Sister Cross was a callback to the canonical Sistermon trio's signature move, with the partial echoes of Noir and Ciel allowing Blanc to channel all three sisters' attack patterns simultaneously. The Magic Card Civilization had registered the technique faithfully, including the damage scaling that came with three-sister coordination.
He looked up at the suspended golden clock. Phase One was now past its midpoint, with roughly six hours remaining of the original twelve.
He returned to crafting without delay.
Building Sistermon Blanc had consumed about two hours. Combined with the time spent on the Digital World worldview and the D-Ark construction, slightly more than half of Phase One had elapsed.
But he wasn't going to stop here. He had committed to a full-portfolio crafting plan, and the remaining six hours were the most critical part of the schedule. The cards he was about to build were the ones that would push the entire Digimon system from "interesting demonstration" to "revolutionary deployment."
He needed Evolution Cards.
Capital Card Master Association.
"Luke is starting on a second card?"
Edmund Hargrove's voice was wholly impassive, but Roland recognized the level of attention his father was giving the monitoring feed. Edmund was watching with the focus reserved for genuinely unprecedented situations.
The first card construction had been the Sistermon Blanc. That much was now established by the creation pillar that had erupted moments earlier. What Edmund and Roland didn't know was what had happened during the silent construction before that, the D-Ark process that had completed without a pillar. They had defaulted to assuming the silent construction was a failure.
The first successful card was already a remarkable Phase One performance. Luke's apparent intent to immediately begin a second card construction, when most candidates were just finishing their first, was outside expected patterns.
"At least he didn't get rattled by the first apparent failure," Roland said. "Though I don't actually know if that was a failure or not. He's not behaving like someone who failed."
"He's behaving like someone with a plan," Edmund corrected. "Whether the earlier construction was a failure or not, he doesn't appear to consider it one."
Roland processed that.
"How does someone Luke's age have the composure to react to a setback with this much equanimity? Even Ellie, with all her preparation, wouldn't have shrugged off a botched construction this calmly."
"Luke's actions consistently defy expectation. Even I can't read what he's planning."
Edmund leaned back fractionally in his chair.
"Keep watching. I have a feeling he's going to produce news that reaches well beyond this exam season."
Inside the exam space.
Luke had already begun the next construction.
「 Evolution is the foundational principle of Digimon power growth. 」
「 Digimon accumulate data through combat. When the accumulated data crosses a quality threshold, the Digimon undergoes phase change, evolving into a higher-tier form. This is the baseline evolution pathway. 」
「 Beyond baseline data-accumulation evolution, Digimon can undergo specialized evolutions through D-Ark facilitation. These include Armor Evolution, Jogress Evolution, Burst Evolution, X Evolution, and others. 」
The background data structured itself smoothly. Evolution was, and had always been, the central theme of Luke's Digimon design. The current card was the next major piece of infrastructure: a dedicated Evolution Card that would allow Rookie-tier Digimon to ascend to Champion form on demand.
「 Hyper Evolution Unit S: Contains data substrate sufficient to elevate Rookie-tier Digimon to Champion-tier form. 」
「 Through D-Ark card-swipe interface, the registered Digimon absorbs the encoded data, breaking through existing tier limitations and ascending to a higher-tier configuration. 」
The D-Ark provided the card-swipe interface. The Hyper Evolution Unit S was the substrate that would be swipedthrough that interface, embodying the evolution data in physical form.
Luke was building the consumable that would unlock his Digimon's first major evolution step.
「 Card background accepted. Please complete the card image and add materials. 」
Unlike the Sistermon Blanc or the D-Ark, the Hyper Evolution Unit S didn't have a clearly anthropomorphic or device-shaped image. Its visual representation was a ring radiating dense data patterns, light and information spiraling outward from a hollow center in concentric layers. Functional. Abstract. The visual matched the card's nature as a data substrate rather than a physical artifact.
Luke fed the prepared materials into the Card Editor. The multi-hued solution dyed the data ring in layered colors as each material integrated, mystical and faintly unpredictable.
「 Construction successful. Mana backflow received. 」
「 Hyper Evolution Unit S 」 Type: Evolution Card Effect: When swiped through the D-Ark, releases stored evolution data into the registered Digimon. Per the Tamer's intent and the Digimon's environmental adaptation parameters, a Rookie-tier Digimon evolves into a Champion-tier form for a limited duration.
"Sistermon Blanc can now access Champion evolution through this card," Luke murmured, satisfied. "And because of Network Evolution, the specific Champion form she takes can vary based on environmental conditions."
Champion-tier output, by Luke's mental model, was solidly within mid-tier card brackets. Whether Blanc's Champion form could match or surpass Mana directly was still untested, and would depend on which Champion form the evolution selected for any given engagement.
He set the Hyper Evolution Unit S aside and moved immediately to the next construction.
The Hyper Evolution Unit S alone, plus Sistermon Blanc at Rookie tier, was a strong combination. But it wasn't the ceiling. Champion-tier was the next rung up the ladder, not the top of it. He had more to build.
