(Background; "Tappy" Font

Tappy Font is the youngest among the Font Brothers. At a very young age, he has a soft spot for science. He would linger and tinker in laboratories he wasn't supposed to be in. He also was a clever child, quickly solving riddles. When he grew up, He decided to take two jobs at once, being an alchemist and a detective. In result, He has a great background, being an master alchemist and detective. Though he's great at doing his work, he tends to do it alone. He appears to be distant and avoidant from his siblings, he intends to be left alone most of the time.

Despite his name, no one besides his siblings actually knows his real name. He only took the name "Tappy" as a nickname. But why Tappy? That sounds so stupid for a nickname. The case is, he kins himself to the Observer of Happenings, Tap. He thinks both of them are similar, both in personality and nature. Hell, he even thinks he and it are one.

He once told himself that one day, he would flee from the Font Manor and pursue his dreams. Then, it happened. Tappy ran from the isolated manor, and finally witnessed the real world. He then took the opportunity to find ingredients throughout different parts of the world for his alchemy. After a decade, he eventually came back to the manor, only to not be accepted and seen as a traitor to his family. As of now, Tappy is a professor of science in a prestigious school.)
