Constellation:

Character:

The main protagonist in Letter Bee. He is a young boy with a very focused mindset, regardless of what situations he gets into and always focuses on delivering the package. He has a special gun called the Shin Ganjuu, literally the "heart bullet gun" where he loads a "fragment of heart" into the gun, then fires it at the target. He is seemingly being able to control the direction of the shot.
