Isaac & Miria

Isaac Dian and Miria Harvent are a nonsensical thief duo who accidentally become complete immortals in November 1930. Isaac and Miria are a pair of idiotic and eccentric lovers who dress up in costumes and commit strange robberies in Prohibition-era United States. In 1930, the duo are two of many characters who mistake an immortality elixir for alcohol and drink it at a celebration, inadvertently gaining immortality and eternal youth (only they don't know it, which makes it all the more comical). The duo commit a variety of eccentric robberies, including attempting to steal time by stealing watches, trying to stop anyone from entering a museum by stealing the entrance and stealing the Genoard family fortune to prevent the family from fighting over it

Appearance

Isaac has bushy brown hair and brown eyes (blue in the anime and 2015 manga), while Miria has straight blonde hair and brown eyes. They are often mistaken for performers because of the variety of disguises they employ during their heists, such as dressing up as mummies or as the Tramp

Personality

Isaac and Miria are both extremely charismatic and vivacious, spreading happiness to anyone and everyone they meet without conscious effort. In the process, they often befriend all manner of unlikely people including the likes of famed hitman Ladd Russo and stoic assassin Chané Laforet. That their personalities remain unchanged into the early 2000s is a testament to their indomitable will, Miria exhibits a complete trust in Isaac and supports anything he says no matter how ridiculous it is and often goes as far to mimic his body language and his speech, although she often does not really know what she is saying. Although the pair are very idiotic, Isaac is not completely stupid and there are occasions that shows that he displays his inner intelligence. While Miria tends to follow Isaac's lead, she does so not out of obligation or deference but simply because she wants to, delighted in how her partner can make her laugh. When the two are involuntarily separated, Miria weeps when she is out of sight and away from others' prying eyes. With her friends, she puts on a brave front and acts like her typically cheerful self; though terribly sad, she remains sincere in her efforts and her belief that she will see Isaac again. Whether working separately or together, Isaac and Miria are extraordinarily kind people at their cores. On the whole, the couple are wildly impulsive and follow whatever whim has caught their fancy. It should be noted that they are not completely oblivious and certainly not stupid, as others might say. Isaac is a big fan of detective novels

Abilities

Isaac and Miria both possess true immortality, meaning they cannot age, get sick, be injured, or die via conventional means. Immortality aside, they possess an endlessly large amount of good luck, having escaped numerous dangerous situations throughout the series without serious injury. They are also fairly competent thieves
