Rei (レイ), officially Monochroid[Rei] = _Type_iX01[Tsubakura];, is a virtual android, used for the promotion of the Len'en Project series, while also seeming to exist as a character in-universe. They have a Youtube channel and a Twitter account, and they are also listed as a member of Trick Nostalgie.[1]

General Information[edit]


They apparently like humans, money, geniuses, fashion, and games. They act bubbly and use rather broad and expressive gestures. They occasionally say "gero" (ゲロ), which might be either the japanese onomatopeia for a frog's croaking, or vomitting. "Gero" is also listed as one of the things they like.


Background Information[edit]


Their official name is Monochroid[Rei] = _Type_iX01[Tsubakura];, and their nickname is Rei (レイ). The nickname is often appended with the japanese honorific -kun (くん). It's possible that the nickname is somehow related to Tsubakura's bomb, "Monochrome Ray" (モノクロムレイ). Rei, read with the kanji "零", could mean "zero", which may have a connection to Zelo.


They have black hair, black pupilless eyes, and pale white skin. They wear a hat, resembling Tsubakura's, adorned with two dots - one yellow, the other light blue. The eye on the hat blinks along with Rei's eyes. Their clothing looks rather traditional-like.


They have appeared in Youtube videos and made posts on their Twitter account.


They are Mugenri's goodwill ambassador, despite never having been to Mugenri.

Tsubakura Enraku

Many aspects of Rei's character alludes to Tsubakura Enraku, from their name to their design. Rei is rather fond of Tsubakura, as shown from their excitement from posting Tsubakura's themes on their Twitter account, as well as appending Tsubakura's name with "-sama" ()

Yabusame Houlen

When the music theme of a character is uploaded to their Youtube channel, Rei makes a comment about the character on their Twitter account. However, they didn't make a comment about Yabusame Houlen. This might imply that Rei doesn't know Yabusame, or dislikes them.

Suzumi Kuzu

Rei seems to have respect for Suzumi Kuzu, referring to them and their personality "Hamee" with the "-sama" () suffix.[2] They also know of Ardey, and even Benny, referring to both of them with "-sama" as well.[3] They see Suzumi as a genius.[4]
