Noted the August 24 change to healing-item timing and the shorter movement slowdown while healing
11Overview22Koo's command system is the strategic layer that sits alongside Emma's real-time sword combat in Beast of Reincarnation. When the player accumulates enough FP through parrying, they can open Koo's command menu, which slows time and presents a selection of Bloom Arts to deploy. This pause-and-choose structure gives the game its hybrid identity: real-time action for Emma, command-based tactics for Koo.44Command Menu Interface66When activated, the command menu slows time to a near-standstill, giving the player space to assess the battlefield, choose an action, and select a target. The time-slow gives the command interface its hybrid feel. Koo carries six Bloom Arts at a time, swapped from the equipment tab of the pause menu, and the command menu surfaces that loadout so the player can weigh several options before committing. The interface displays available Bloom Arts, their FP costs (shown at the bottom-right of the screen), and target options. Players can also use healing items from this menu, making it a dual-purpose strategic pause for both offense and recovery.7+When activated, the command menu slows time to a near-standstill, giving the player space to assess the battlefield, choose an action, and select a target.

Players can also use healing items from this menu, making it a dual-purpose strategic pause for both offense and recovery. Healing got noticeably more responsive in the August 24 patch: a healing item can now be used the instant damage lands rather than after a short delay, and the movement slowdown while Emma heals was shortened. Both were on the publicly announced list for weeks before they shipped.88The time-slow mechanic gives the encounter a deliberate, paused cadence, and it has a second use the interface does not advertise: because the fight keeps moving while the menu is open, opening it during a boss encounter is a legitimate way to study how that boss is winding up an attack before committing to an answer. While Emma's combat plays like an action game, opening Koo's menu shifts the experience toward a command-driven selection layer. Director Kota Furushima's emphasis on command-driven strategy is clearly visible in how this transition feels: a deliberate gear-shift from reflexive play to strategic decision-making.1010Inputs and the QTE Check1212The command menu opens on Triangle, Y or F once Koo has the FP for something. On mouse and keyboard the Bloom Art has to be hovered and clicked; clicking a highlighted entry without hovering it does nothing, which catches out a lot of players moving over from controller.1414Selecting an art starts a quick-time event: a circle with a highlighted yellow arc, and the input has to land inside it. Failing does not cancel the art. It fires anyway at greatly reduced effect, so a missed check costs damage, status build-up and healing rather than the whole turn.1616Full Bloom1818The FP bar is not just a gate, it is a multiplier. Damage and stagger scale with how full the bar is when the art goes out, and at maximum FP Koo enters Full Bloom, where a Bloom Art lands with double damage and half again the stagger. Parries stop paying FP once the bar is capped, so sitting at maximum is wasted income rather than banked power.2020Source of FPDetailParrying as EmmaThe main source. Block timed as the attack lands adds FP to Koo's bar at the bottom right of the screen.Recovery BoostAn Emma skill under the Entanglement Overdrive branch. Chance to restore FP whenever an enemy drops.PhotosynthesisA late Koo skill under the Pounce branch that raises his maximum FP. Expensive at 80 skill points.Spirit StonesSharpshooter, Entangled Parry, Entangled Dodge, Entangled Riposte and the rest of the Entangled family each return FP off a specific trigger.2222Bloom Arts and Quick-Time Events2323Bloom Arts are Koo's special abilities, each consuming a specific amount of FP. After selecting a Bloom Art, the game triggers a quick-time event (QTE) that the player must complete for the ability to take effect. Specific Bloom Arts shown in gameplay include abilities that deal fire damage, deliver high destructive damage to multiple foes, group enemies together through crowd control, inflict poison damage, and launch enemies airborne. The available Bloom Arts expand as the player invests in Koo's skill trees, whose branches are gated on his own attribute spread rather than on named combat lanes.2525Choosing which Bloom Art to deploy at any given moment is one of the game's key tactical decisions. A player surrounded by enemies might choose the crowd-control grouping ability to cluster them together before following up with a high-damage area attack. A player facing a tough single target might select fire damage for sustained pressure or a launch ability to create an opening for Emma's aerial combos. The QTE layer adds execution skill on top of the strategic selection.2727Koo's Own Skills2929Not everything Koo does comes out of the command menu. His Strength branch is mostly passive work he performs on his own initiative, while the Vitality and ranged branches are largely modifiers that hang off his Bloom Arts.3131SkillWhat It DoesPounceInstant kill on a weakened enemy when Koo is told to run ahead. The root of his Strength branch.Attack DogRaises Koo's damage while he is fighting alone after a run-ahead order.Lay Landmine, Lay Flame TrapKoo occasionally seeds the ground with explosive or fire traps.GuardGrants Emma Armor and Fortitude buffs each time a Bloom Art goes off.TauntPulls enemy attention onto Koo.Snatch, StealTakes items off enemies during a fight.PhotosynthesisRaises Koo's maximum FP.3333Rapport matters here too. Raising it through petting, treats and the shower aboard the ship opens more of Koo's item and skill slots, so the relationship track feeds directly into how much of this list is available at once.3434Mods System3636Each Bloom Art can be further customized through mods, which alter the ability's secondary effects. Known mod effects include:3838ModDescriptionHP regenerationEmma regenerates a small amount of HP per hit while the Bloom Art is active.VigorProvides a damage buff against status-afflicted enemies, rewarding players who layer conditions on targets.FP generationGrants Koo additional FP for hits against enemies with specific status effects (such as burned enemies), creating self-sustaining ability loops.4040Mods add a layer of build-crafting on top of the Bloom Arts themselves. Two players using the same Bloom Art with different mods will see meaningfully different results. This customization depth means that even within a single skill tree path, there is significant room for personalization.4141Skill Tree Integration4343Both Emma and Koo have three skill trees each, upgradeable with SP (Skill Points). Options range from melee combat to stealth and long-range abilities, with passive skills that boost stats and recovery. Koo's close-range support tree provides abilities that complement aggressive melee play, such as crowd control and stagger effects. The long-range support tree offers abilities that maintain distance and punish advancing enemies. The stealth support tree provides distractions and repositioning effects that enable covert approaches.4545Emma's abilities draw from a separate resource called the Entanglement Gauge (a bar displayed at the bottom center of the screen), distinguishing her skill usage from Koo's FP-driven Bloom Arts. Investment in Koo's trees synergizes with corresponding investments in Emma's trees. A player who commits to both close-range trees for Emma and Koo creates a cohesive melee-focused build where parrying fuels devastating close-quarters Bloom Arts. As Furushima has said: "I want players to enjoy trial and error, trying different fighting styles next time, or changing Kuu's skills."4747The Hybrid Loop4949The command system completes the combat loop that begins with Emma's parry. Emma fights in real time, parrying to generate FP and triggering Spirit Stone compounding effects. When enough FP accumulates, the player shifts into Koo's command mode, selects an ability, deploys it, then returns to real-time combat. This back-and-forth between action and strategy is the defining rhythm of Beast of Reincarnation, and it distinguishes the game from both pure action RPGs and traditional turn-based games.5151Post-Launch Changes5353Version 1.0.8 increased both the damage and the HP recovery on Bloom Arts across the board, and fixed a performance problem with the End of the Line mod attached to Kiku: Bloom Strike. Version 1.0.7 fixed a bug that left Emma unable to interact with anything after a Bloom Art was cancelled. Both are listed in full under Post-Launch Updates.
