Red Text
Everything is blooming most recklessly.

This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.

A Jakobs-made sniper that fires a straight-line explosive projectile and, on the critical immediately after reloading, scatters sticky projectiles to nearby enemies. It combines Jakobs’ characteristic high single-shot damage with an explosive “ricochet and spread” element, making it a unique weapon that excels at crowd control.

🧩 Origin of the red text “Everything is blooming most recklessly.” is a passage from poet Rainer Maria Rilke’s letters (continues with “…if it were voices instead of colors, there would be an unbelievable shrieking into the heart of the night.” confirmed by multiple quote databases). The weapon name “bloom” (to blossom / explode / disperse) and the unique effect where explosive projectiles ricochet and spread as if blooming chaotically (Bullet Pollinator = pollen mediator) are linked via a blooming metaphor.
