Calvin Azuma (Caleva Azucar [Fantroll])

As much of an enthusiast for the paranormal as his human counterpart, Caleva spends most of his time exploring haunted hotspots and recording his findings for his own benefit and no one else's. Thankfully ghosts are pretty much confirmed real in Homestuck so he doesn't need to go convincing people they exist. That said, he still doesn't care to interact much with the living, unless he's bugging highbloods to give him research grants. What's he using the money for? Who knows. Buying sweets, probably. A studious boy's gotta eat.
