#04 THE A.I. TYPES
-----------------------------------------------------------------------------------------------

In "Azur to Crimson", KAFU gets told by Kiritan that Zunko and Itako are being jealous of her because she has an AI type they don't have. However, when you look at the truth, Zunko and Itako actually possess an AI. Just they don't have the same type as Kiritan does actually have.

There are several types of AI:

- the N type is one that is possessed by all Tohoku sisters. Nynthixia thinks of them as very poor quality ones and denies working with these.
- the V type is not accessible to anyone, but was used in necromancy projects. No more info was given. The judgement of quality by Nynthixia is quite neutral.
- the C type is currently possessed by Yukari, Kiritan and KAFU. Soon IA and ONE will have one as well. Akari, Zunko and Itako are also potential candidates for these. For Nynthixia its quality is "sufficient".
- the S type is considered by Nynthixia as the "S-tier AI type". It is possessed by Saki, very soon by ROSA, and maybe, someday, CUL will also have one.

So, the reason why Zunko and Itako are jealous to Kiritan is because Nynthixia denies working with N type AIs, and would rather them to acquire C type AIs. Team behind the Tohokus, you now know what to do to "heal" the girls you are in charge of in this world...
