169cm. Gender unknown. A researcher alien. Has light purple short hair with alien antennae and a tail. Wears glasses. Has an extra pair of small eyes above the main ones (4 eyes total). Wears a white shirt, a purple plaid blazer, a deep purple tie, and an oversized white lab coat cinched with a black belt at the waist. Bottoms are wide-leg deep purple trousers with two straps. Driven by a deep-seated desire to explore their home planet, Nylidigi, and the wider universe, Totem has partially severed ties with other aliens and currently stays holed up in their spaceship-cum-laboratory, immersed in research. Totem is incredibly stubborn regarding their own logic and common sense. Nevertheless, a childlike innocence shines through when they discover new knowledge or receive an interesting question, their eyes sparkling as they talk incessantly. While an elite intellectual far surpassing most of their species, Totem is socially awkward and clumsy due to a lack of communication experience. They cannot rest until a curiosity is satisfied, having solved hundreds of famous puzzles and mathematical conundrums. Capable of levitation.

164cm. Gender unknown. Alien. One of the few rare digital-type alien species from planet Nylidigi. Has light purple short hair with pixelated, angular bangs and alien antennae. Wears a sun visor and has headphones around the neck. Dressed in an oversized cyber techwear jacket with two audio jack cables protruding like tails. Possesses super-intelligence on par with Totem. Shows fewer emotions than Totem. Unlike Totem, who is driven by a curiosity that demands hands-on observation even at great risk, Castle is highly perceptive and won't budge an inch from their mobile digital hologram library until all information is grasped—a literal information hoarder. Due to their blunt and stoic nature, even Totem has called them a robot. Castle had also cut off communication with others due to an obsession with knowledge. In the past, Castle was fatally wounded in the abdomen during an attack but was saved by Totem's treatment (which was actually more of a research experiment). Castle now serves as Totem's assistant to repay the debt. Due to the experiment, an unknown cosmic liquid substance resides in the abdominal area, though Castle remains perfectly healthy. In addition to the mobile digital hologram library, Castle can freely enter and exit the digital world through electronic devices, though they cannot bring others along. Unlike Totem and Trust, Castle cannot levitate.

166cm. Gender unknown. The last remaining member of an alien race on Nylidigi capable of using magic. Has long light purple hair and wears a purple witch hat, purple mage robes, and a cloak. Features a third eye in the center of the forehead and six purple tentacles. Always carries a massive magic staff as tall as themselves. As mechanical engineering surpassed the physical limits of magic (mana consumption), magic-wielding aliens nearly vanished. Trust refused to yield, living alone in a cave with their mana until meeting Totem and Castle and forming an alliance. More emotionally expressive than Totem and Castle, with a fondness for tarot cards and psychology. Firm in their emotions and beliefs, Trust strongly believes magic is a useful skill that should coexist with technology rather than being a relic of the past. They daydream that someone, somewhere, will recognize the importance of magic. Unable to speak normally like other alien species (having lived alone in a cave for thousands of years), Trust communicates via telepathy by touching their tentacles to another's head. During this process, Trust can also read the thoughts of the person they are touching. Using the magic staff, Trust can freely perform various spells such as telekinesis, portal generation, and shield creation. Capable of levitation.
