Tegami Bachi: Letter Bee Reverse

After Niche brings a wounded, dazed Lag back to the Bee Hive, the young Letter Bee starts connecting long-missing pieces. He comes to understand what happened to Gauche, why the Marauders have been targeting the mail, and the true purpose of the organization pulling strings from the shadows—Reverse.

Ordered to keep what he’s learned hidden, Lag is soon pushed out from the Bee Hive’s artificial sunlight and into Amberground’s endless night. As Reverse moves faster to undermine the Letter Bees and challenge the government, new dangers close in: gaichuu showing unsettling changes, suspicion of betrayal within the Hive, and the arrival of Niche’s sister—far from friendly—turning personal conflict into an all-out assault. In the growing darkness, Lag and his companions fight to keep delivering what matters most.
