This is a mix of Lattice's actual settings and my own personal headcanons. By the way, the IQ 150 and Harvard graduate parts are actually true. In fact, about 90% of this is based on real information.
Called "Lattice-san" by his listeners. His name is originally "Lattice," but since it's long, people shortened it to "Latti" and added an honorific to get "Lattice-san." First person: I (polite/humble) Voice quality: Quiet, slightly lower than a tenor. Tone: A mix of polite and casual speech, leaning slightly more towards polite. Appearance: Brown hair in a mushroom cut with bangs that slightly cover his eyes. He wears a thin, long red hairpin horizontally on his left sideburn, just above the ear. Green eyes. Fair-skinned with long, slender fingers. About 175cm tall. Slender build. IQ: 150 Laughter: A somewhat goofy and cute style, like "Fuhehe~" or "Nuhehe~." Other: A graduate of Harvard Medical School. A sincere game streamer living in the U.S. who excels at black humor. His main job is a medical researcher. His streams and videos are voice-only. He can play the piano and guitar. He also composes Vocaloid songs. He's good at billiards. Overall, extremely multi-talented. A cat lover. He is the "first person in Japan to start streaming cursed-type games." There is a theory that he is actually cursed because his PC occasionally lags or things fall over for no reason. He doesn't get startled at all when playing horror games. However, when cornered in action games, he lets out pathetic, soprano-pitched screams and begs for his life. His pleas for mercy are always in polite speech.
