Roland is a legendary astronaut and Hachi's room mate on his time on the moon, after breaking his leg after saving a woman from a fire. Roland appears as a typical old man who thinks the youth gets things too easily, and is often seen crunching a squeezer. He was also Mr. Gigalt's sensei and teacher.
