「WHAT IS EXACTLY A HUMANOID」

Humanoid refers most commonly to an android or a gynoid looking like a human and given systems that imitate the ones of a human (respiratory, bloodstreams etc). Their body has been made to ressemble as much as possible to a human body. However there are few differences that can help to distinguish them.

- Ritsu's chest is actually made of missiles. Ritsu's legs are also hiding jets.
- Momo's head is detachable.
- Aika's body is the one of a robot. Her mind is clearly a sort of artificial intelligence in a robotic body.
- in the case of musical isotopes as well as POPY and ROSE, their bodies are actually a bit unclear. Some of their systems were indeed replaced to get ones similar to human ones. But they have a stronger connection to electronics in some way, and their abilities make them hard to define as humans.
- #kzn has a robotic body. Her mind is the result of an artificial split of her creator's.
- Chis-A is an artificial intelligence that gained a robotic body.

The thing the most common to humanoids is the bloodstream. Their blood is a special type called "R" and is thus not compatible with human blood. Main difference is most of the blood cells. But their bodies were programmed to react the exact same way as a human body. However forget about any "Artificial Biological Tissue" white stuff, their blood is still red like most organic creatures.

They are immune to most of viral human-specific diseases. Which means viruses affecting humans can't access their systems because they lack receptors and the biological material needed for a virus to replicate. They are more resistant to the other types of diseases, but not immune to all of them.

Their brain have a greater memory than the human one, but is mostly programmed to also replicate functions of a human brain. Just look how #kzn was able to memorize very complicated old languages... Within few days only!

All of these things seem however unable to make them immune to corruption. In some way, corruption tends to insert "artificial data" into the minds of humanoids to twist their personalities like they would do on a more organic being.

「POLYMORPH BEINGS」

Some characters do not have a fixed appearence. They are considered as polymorph beings. They tend to adopt a "stable" appearence but can actually change some details just by using their abilities. However, this makes them very difficult to estimate their age since they can take the form of a kid, an adult, an elder person as they wish. They generally just don't take the form of other existing people and have to stick to their gender: these are their only limitations. Genderless polymorph beings can adopt a male or a female body and thus are only limited to not take the form of someone else who already exists.
All the polymorph beings who joined the castle however are female ones. Male ones also exist of course.

The origin of polymorph beings is still unknown. They could be as old as the universe itself, as old as the Earth itself or very recent. That is why they are considered "ageless". They however like to have a birthday, like to replicate organic people's. For this, they tend to use the first date they remember to awaken.

「ALIENS?」

The team currently has 4 aliens: Stella, Tianyi, ONE and IA.

IA and ONE are from the same planet, Aria. They typically have human-like forms and have bodies very similar to humans. They are also immune to viral diseases but can still be affected by other disease types (bacterial, fungal etc).

Stella's origins are apparently from a star. Also her alien origins could be the reason how she could easily change her appearence, but not in the same way as a polymorph being.

Tianyi's planet is unknown, however, she also can be refered as being an angel and as such, not exactly from Earth.
