«Anneal Blade» is a one-handed sword that is obtained as a reward for the «Secret Medicine of the Forest» quest; the quest NPC requires the player to retrieve a medicine ingredient («Little Nepent's Ovule», indicated on the quest mob by a large blooming flower) from a rare variant of Little Nepent (a plant-type mob). The «Anneal Blade» can attempt enhancement eight times, with the number of successful fortifications listed after the weapon name.

Kirito owns an «Anneal Blade +6» (3S3D). It was later boosted to +7 in Material Edition 9.
