2x4 - Tegami Bachi: Letter Bee

"Get away from here"... The boy Lugh works together with an old man he calls "Grandpa" in an imagery lighthouse built out in the wilderness, but he keeps hearing voices from somewhere. Around the same time, Jiggy Pepper is passing by the area on a delivery, and notices that a Gaichuu, Korona, has made a nest on top of the imagery lighthouse. Riding his "iron horse" up the imagery lighthouse, Jiggy Pepper's shindan Lapis Lazuli explodes!
