Her first name is transliterated as "Harry" in ViVid Strike! and INNOCENT cards. Notably, "Hallie" was formerly used by a few cards in their 2013 editions, and was later amended as "Harry" for consistency. Her family name is probably a reference to the Subaru Tribeca, and has been misspelled as "Trideca" in ViVid Strike! She is also nicknamed Buster Head (砲撃番長(バスターヘッド) Basutā Heddo) due to her battle style and skills.
