Originally called Sais, she was renamed to Saisei due to Kanji/Hiragana problems. Putting her whole name together, it can mean either "Rebirth Lost" or "Lost Rebirth/Reincarnation" (depending if you read her surname or given name first).

History: A problem with Saisei is that because she's a "Lost" or "Incomplete" reincarnation, she lacks other emotions. If she does anything that resembles these other emotions, she's just acting it out to feel like she belongs. When she's showing no emotion, she's most likely seen playing with a PSP and being extremely quiet, to the point that her responses to conversations are either nodding, shaking her head or going "..." .

Together with Yume Utao, Midori Kichona, and Tsuki Taiyo, they form TYMS.

Please note: Saisei never shows her ears, so if you were to make art of her, please don't show ears on it. Her hair will always hide it.

Voice Configuration


The original ACT1 voicebank has a poorly edited oto.ini (which is the fault of the author), causing Saisei to mispronounce the consonants of various notes.

The link to the download has been taken down.


Her ACT2 voicebank was made to fix the pronunciation problem.

One might notice when using Saisei that there are robotic ticks and background noises. It's part of her voicebank. Since Maigo Saisei means 'lost reincarnation/rebirth' (or 'rebirth lost' if read as Saisei Maigo), it's supposed to reflect on that slight imperfection.

Her singing with the ACT2 voicebank can be heard here (She's singing Toeto) :
