Beast of Reincarnation Koo Skills: Bloom Arts & NG+
Koo’s Beast of Reincarnation progression is tied to the companion loop rather than Emma’s blade upgrades. The official Steam description says the player commands Koo’s techniques, while the Steam achievement guide separates all Koo skills from all Koo flower techniques and tracks them with different achievements.

| NG+ boundary | Some Koo skills and techniques are reported as second-run progression |

How to plan the Beast of Reincarnation Koo tree
- 1.Spend Koo resources around the encounter: healing, status, elemental pressure and damage do not solve the same problem.
- 2.Track Floral Profusion separately from Giant Tree in Bloom so a complete skill tree is not mistaken for fully upgraded flower techniques.
- 3.Use the visible enemy weakness to choose a Bloom Art, then complete the prompt rather than treating every technique as interchangeable.
- 4.Expect a completion build to extend into NG+ if a node is still unavailable after the first ending; the Steam guide reports that boundary but not every unlock order.
- 5.Link Koo’s build decisions back to Emma’s parry and entanglement loop because the official design presents them as one combat unit.
Evidence boundary
The official Steam listing confirms Koo commands techniques in the hybrid combat system. Achievement names and the roots/tree/NG+ boundaries come from Steam Community guide ID 3777472649, with Bloom Art timing covered separately in the site’s sourced combat guide.
