To put it simply: "A taciturn former Sinclair from a 'what-if' world of A Certain Sinclair." Full Name: Silter Miere Personality: Taciturn, but speaks properly to those he likes or is interested in. Conversely, he is silent toward those he dislikes or is uncomfortable with, only speaking occasionally to allies. Gender: Male Weapons: Halberd and Bastard Sword Clothing: A black military-style shirt under a dark yellow jacket, dark yellow pants, black boots, and black gloves. He wears a black harness from shoulder to back to carry his halberd and bastard sword. Likes: Strawberries, fluffy things Dislikes: Being asked why he is so quiet Hair: Slightly messy mash-short hair with a small ponytail. Color is dark yellow with a hint of green. Eyes: Pale dark yellow First person: I (soft) / I (rough, casual) (Usually rough) Second person: you (soft) / you (blunt) / No honorifics / -san (Usually no honorifics, but uses 'you (soft)' for strangers) Speech style: Slightly polite but casual (?) Other: Old bandages are wrapped around his halberd and bastard sword and can never be removed. According to him, the bastard sword was a spare given by A Certain Sinclair, while the halberd is his own. He is quiet because he was bullied in the past for his timid way of speaking, though he has overcome that timidity now. He is actually the Color Fixer "The Green Bandage," named so because mixing blue into green results in yellow... yes, because the smoke looked blue to him, he became yellow. He is a version of Sinclair from a timeline where he stopped the Smoke War single-handedly, changed his name, and traveled the world. Unlike the other two, he is in a special state not included in AUs or Identities.

To put it simply: "A tsundere from a future in another world who has a foul mouth due to a heavy past, but everything he says is actually kind." Real Name: Dante Hellsheaven Personality: Foul-mouthed, but kind underneath, often giving roundabout compliments. Gender: Unknown Weapons: Can use anything, but primarily uses knives. Has a habit of using a reverse grip and is still powerful. Clothing: Black shirt with a red scarf, green jacket, black pants, and a black belt. Red shoes with white stripes and white gloves. The belt has a small storage box for his knives. Likes: Strawberries Dislikes: Lemons Hair: Slightly messy short hair. Color is green. Eyes: Red First person: I (rough, casual) Second person: No honorifics / you (blunt) (Usually no honorifics, uses 'you (blunt)' for strangers) Speech style: Casual Other: Wears glasses when in "off-mode" while resting from exhaustion. It's not because of poor eyesight. He is actually a feline fallen angel and the administrator of Heaven and Hell; he is the one who decides who goes where. He is in the mortal realm simply to kill time. He is the oldest of the Future Trio, though everyone's exact age is unknown. He lost his younger brother in the past, which traumatized him regarding loss; as a result, he tries not to fall in love with anyone. He has various AUs and is often called the Guardian Deity of AUs, though he mostly just manages his own. How are Mirasoni's AUs different from Sans? "Every AU features Mirasoni instead of Sans, they have nicknames, and most are the strongest. Example: Error Mirasoni = Error (nickname)."

To put it simply: "A Sinclair from a future where war broke out and left him all alone; he has no mercy for prosthetics but is still kind." Real Name: Emil Sinclair Personality: More helpful and kind than the other two. Gender: Male Weapons: Halberd and Bastard Sword (same appearance as Silter's) Clothing: A somewhat complex black shirt with a black belt and a harness for the halberd across his shoulder and back. Black pants and black boots. He wears a dark yellow jacket and black gloves. Likes: Nothing in particular Dislikes: Nails, prosthetics Hair: Slightly messy short hair with a small ponytail. Color is deep golden. Eyes: Same as hair color but slightly paler. First person: I (soft, polite) Second person: You (polite) / No honorifics / -san Speech style: Polite (Desu/Masu style) Other: Usually just called Sinclair. Sometimes mistaken for Silter because they look similar. He is the Sinclair from the canon route who ended up alone after the Smoke War. Unlike the other two, he explicitly identifies as an adult. Unlike Mirasoni, this is a "what-if future" world of Sinclair, so he is treated as an "Identity" rather than an AU. What is an Identity? "To put it simply, it's a version of yourself from a 'what-if' world reflected in the Mirror World. However, it's unknown if that version will ever manifest in reality."
