Japanese Names! because my autism knows no bounds (most of this work done by @rennanttennant , thanks pookie <3 /p)
Tuse: ワツカイ (Watsukai), took my full online name (iwontusethis), translated it to japanese (これは使いません; kore wa tsukaimasen), and removed the equivalent of iwon and this to be left with the closest translation to "Tuse"
Mobi: ケイタ (Keita), derived from 携帯 (keitai), short for 携帯電話 (keitaidenwa), like how Mobi is short for Mobile as in Mobile Phone
Ray: ヒカル (Hikaru), didnt wanna just translate the name directly, so to keep both the "normal name" theme with their little quartet and keep the light theme, a japanese name meaning light, 'hikaru' (光)
Tycon Twins: カ タイコン & ジョー タイコン (Ka Taikon & Jou Taikon), the only characters who are transliterated, to emphasize them being Not Like Other Darkners, though the first names were changed to make the X.S. Mining name pun work, now being a play on 過剰採掘, which just means "overmining". As for Tycon Soul X, he is called タイコン ソウル 力. the first part is タイコン ソウル (Taikon Sōru) as you'd expect, but instead of having カ (Ka) in there, it uses the incredibly similar 力 (Chikara), which means strength, power, or force
Habub: スバアラシー (Subaarashii), portmanteau-esque mix of 砂嵐 (sunaarashi) meaning sandstorm and 素晴らしい (subarashii), typically meaning excellent/wonderful, but its obselete form is extreme/terrible, which fits since habub is haboob + hubub
Styla: ペンタ (Penta), i tried my whole damndest to avoid transliterations, but alas, they just dont have a unique word for stylus or drawing tablet or anything, so this is just a shortening of "pentaburetto" (ペンタブレット) which means pen tablet
Blinkerton: マタタンテー (Matatantei) due to being named after an actual company (pinkerton if it wasnt obvious), i had my work cut out for me, as no such equivalent company exists in japanese, so i made do with blink (瞬き/mabataki) and detective (探偵/tantei)
Nick: コモ (Komo), with his shop, (Nick's Knacks) is now コモの入れ (Komo no Ire; Komo’s Container)
Dandy: ゲンキ (Genki), admittedly the weakest name, but so was their english name so no harm no fowl, its a name that means healthy, energy, and the like, fitting with them being an inhaler that likes seeing people have fun, meanwhile the 気 part of it (when in hiragana and not katakana) means air, which makes sense with an inhaler
Monica: モニカ (Monika), a shortening of harmonica (ハーモニカ), as is her normal name
also for funzies! personal pronouns!
Tuse: おいら (oira), get your #oirashocks ready bc im southern asf
Mobi: わたくし (watakushi), feels stiffly official enough
Ray: Their name / じぶん (jibun), changes after getting the crystal to show the difference
Tycon Twins: ちん (chin), archaic pronoun used only by the emperor, a 'royal we', Soul X (and Drifter S) uses おれ (ore) due to being solo
Habub: N/A, but i like including it anyways
Styla: オラ (ora), cowboy lady obviously used the cowboy lady word
Blinkerton: ほんかん (honkan), a pronoun used by government officials
Nick: わし (washi), nick is old and retired so itd make sense
Dandy: ボク (boku), iunno how to explain it but it feels right
Monica: あたい (atai), shes casual, what can i say
