- Manila Karasu <
Manira Karasu>: Sailor Lead Crow has this name. It is not known why Manila (
Manira) is in 
Manira Karasu.
karasu means crow in Japanese.
- Chu Rat <
Ch
Ratto>: Sailor Iron Mouse has this name. Ch
comes from ch
ch
naku, which can describe a mouse squeek. Mice and rats are in the Muridae family.
- Half Bird <
H
fu B
do>: Sailor Aluminum Seiren has this name. Seirens were thought to be part bird in classical mythology. One site shows Half Bad (
H
fu Baddo) instead of the more accurate and relevant Half Bird (
H
fu B
do).
- Miss Butterfly <

Misu Batafurai>: Sailor Metal Papillon (

[sic] S
r
Metaru Papion) has this name. The name Miss Butterfly may have some relationship with the opera Madama Butterfly by Giacomo Puccini.
- Kalunite (Nite Luka/Naito, Ruka) <
(


Naito Ruka)>:
Karunaito approximates the name Kalunite, the name of a kind of a mineral. Notice how we defined certain parts of
Karunaito to approximate Kalunite: a) the
Ka in
Karunaito approximates the Ka part of Kalunite, b) the
ru in
Karunaito approximates the lu in Kalunite, and c) the
naito in
Karunaito approximates the nite part of Kalunite. Therefore, it makes sense that the
Naito in 


Naito Ruka approximates Nite (nite [from Kalunite] used as a name), and the
Ruka in 
Naito Ruka approximates Luka (the ka and lu in Kalunite switched around). This name could be Ruka Naito if it is supposed to be a Japanese one. One site uses Night Luka for no good reason other than the fact that
naito can approximate night. Night does not seem to be relevant to this name. Knight is not as relevant as the nite in Kalunite is.
- Hiddenite (Yano, Hideo) <
Hidenaito (
Yano Hideo)>:
Hidenaito approximates the name Hiddenite, the name of a kind of mineral. Ya means night, no means field, hide means England or English, and o means male. The
Hide in this case has the same transliteration as the
Hide part of
Hidenaito.
- Hematite (Taitohi, Shinhachiro) <
Hemataito (
Tait
hi, Shinhachir
)>:
Hemataito approximates the name Hematite, the name of a kind of mineral. The readings of the kanji are uncertain. It is also not certain where the separation between the surname and the personal name is. Tai refers to a stand, t
means east, hi refers to flatulence, shin means true, hachi means eight, and r
means son.
