Artist's commentary
[Characters] (Sequentially from the left)
Stig: Whether she is human or machine is unknown. She is taciturn and expressionless. She is just someone who is fast when driving cars. It seems she's usually in the clubroom, but sometimes she's ordered out by Remy to run errands to the school store.
Remy Kurakuson: "Kurakuson" (Clarkson) is made up of three kanji that can be read in that manner, although they don't mean much on their own. ("Warehouse-music-village".) "Remy" is in phonetic Katakana. The club president. A manly tsundere, a "power" fangirl, and eco-hater. For some reason, pianos fall on the things she doesn't like. Her father is a pilot. (Works for Careless Airlines.)
Satsuki Satsuki: Spelled as the kanji for the month of May, and then hiragana 'satsuki', which is, again, "May". Club vice-president. She is calm and patient. Because she always maintains safe driving, she's gained the nickname "Slow Angel". Her favorite car is the Dacia Sandero.
Rin Hammond: All katakana this time, like Stig. Also, "Rin" actually comes first, unlike the usual Asian naming order. Standard club member. Small, cute, and after all, a power fangirl. Wears a nekomimi accessory. Once, Remy stuffed her into a jet car, and she almost died.
