And like how all good things start with an introduction, they also start with the first character.
Shown here is Mr. Resident, one of the more prevalent characters in the walls of Tomo, being essentially a bona-fide protagonist for most of the stories. As a person, he tends to be quiet to most, preferring a life more like a "ghost" as he describes it, choosing to wander aimlessly through the halls when not busy with other hobbies, his shy nature coming from a harsh life prior to his arrival in the Tomo Hotel.
On the topic of hobbies, Resident's one of the most talented of the bunch. With a lifetime of experience with music, particularly pianos, much of his time is spent in the theaters, playing the various keyboards Tomo has to offer; in specific, his favorite is the Modular Piano, which he describes as "a limitless synthesizer". To his friends and familiars, he's most known as the musician more than anything else.
Aside from music, he often writes and visits with the small network of friends he has, when he isn't skulking around the hotel late at night for alone time and listening to the hundreds of hours' worth of music he owns.
