Tegami Bachi - Terminology

Terminology

• Letter Bee (テガミバチ, Tegamibachi?): A delivery person who is entrusted with shards of the population's "hearts" in their letters, which they have to deliver despite the threat of armored insects.
• Dingo (相棒, Dingo?, lit. "Partner"): A bodyguard who is picked and trained by a Bee to protect them from armored insects. A dingo can be anything from a dog to a human.
• Bee Hive (ＢＥＥ－ＨＩＶＥ, Yūbinkan Hachi no Su?, lit. Mail House Beehive): The headquarters of the delivery service where all the "Bees" work. Located in Yuusari, the middle-class area of AmberGround.
• Gaichuu (鎧虫, Gaichū?, lit. "armored insect"): Giant insects covered in jeweled armor, said to be spirit insects that lost their hearts. They live in the dark lands outside of the artificial sunlight and attack anyone who travels along the darkened paths. Each Gaichuu that has appeared thus far in the manga is named after an alcoholic beverage.
• Shindan (心弾, lit. "Heart Bullet"?): The "fragments of heart" used when firing the "heart bullet gun."
• Shindanjuu (心弾銃, Shindanjū?, lit. "Heart Bullet Gun"): The weapon Lag uses to combat armored insects. He first loads a "fragment of heart" into the gun, then fires it at the target, seemingly being able to control the shot's direction.
• Spirit Amber (精霊琥珀, Seirei Kohaku?): A powerful amber stone that has the power to allow its user to shoot a heart bullet from its heart bullet gun. It comes in a wide range of colors that each have different abilities. It contains this power because of the spirit insects trapped inside it.
• Spirit Insects (精霊虫, Seireichū?): Extinct insects from ancient times, they have all either become Gaichuu or imprisoned in Spirit Amber.
• Reverse (リバース, Ribāsu?): A group trying to cause a "Reverse" (再生, Ribāsu?) of AmberGround. It is led by a man known as the "Person who was not able to become a Spirit."
• Marauders (略奪者, Ryakudatsusha?): Agents of the group "Reverse" who steal letters from Bees.
• Letter Bullet (手紙弾, Tegamidan?): A bullet used to convey one's heart to another person. A small letter is written and placed within the bullet, with an address to a specific person on whom the bullet will only work. The bullet also stores more "heart" than a normal heart bullet. This is also a physical cartridge with a red liquid within it.
• Picture Letter (絵テガミ, E-Tegami?): A letter written with heart, but that consists of solely an image. Such a letter conveys hopes and feelings of nostalgia, and has a strong message (sometimes) for the receiver of the letter.
