Tegami Bachi: Letter Bee

The Scarlet Red Melody (2x13)

:

On the government's request, Largo sends Zazie in charge of the personnel that will head east to destroy Cabernet. Lag undergoes examination by Dr. Thunderland Jr. after he fired too many shindans. Aria is sent to deliver a letter to Houdai Franklin, a man who worked aboard the airship. Hearing this, Lag sends a reluctant Niche to accompany Aria as her temporary dingo. The duo head for Black Cherry Pond which will lead to Houdai's current residence, which is rife with gaichuu. While crossing the pond, they are attacked by gaichuu Tequila Sunrise. Despite Aria's objections, Niche goes to attack the gaichuu, prompting Aria to use her shingengakki to attack. However she loses concentration as she hasn't attacked for a long time. When the gaichuu captures Aria, Niche sees her memories of the time she grew up and later worked with her dingo, a dog named Bolt. Thanks to Bolt, she plotted a set of safe delivery routes for the rest of the bees. Despite being disappointed she has no worthy skill to deliver letters, Aria continues to rely on Bolt for his support. Niche frees Aria from the gaichuu and encourages her to fight, saying she's the only one to defeat them and translated Bolt's howls that he will always protect her. Aria is encouraged and finally gains the concentration to destroy Tequila Sunrise. A flashback shows Aria worried about Gauche's safety and well-being, while Bolt has to retire from his duties due to old age. Aria wanted to quit but is told by Largo to stay on as administrative assistant. Meanwhile Lawrence talks to Signal, he gatekeeper of the bridge to Bifrost, who is revealed to be supporting Reverse with his brother. Lawrence informs Signal that Cabernet has been spotted and his people will soon direct it to attack Akatsuki.
