Trivia

 * The Kurikaramaru is the only sword in the series with the suffix -maru, which is generally applied to demons (such as Sesshōmaru), young samurai (such as Takemaru), or ships.
 * The Kurikaramaru is the only name in the series which uses more than three kanji.
 * Unlike other swords in the series, whose names are much more straightforward, the five kanji in Kurikaramaru are not meaningful in themselves. Rumiko Takahashi possibly chose the name based on a reference to a japanese mythical sword named Kurikara (倶利伽羅) instead of naming the sword. The name of the mythical sword was historically borrowed phonetically into Japanese from Asian myths where the sword is known as Kulikah due to which the kanji are not particularly meaningful.
 * Kulika/Kulikah comes from the Sanskrit meaning "coming from a very good family" or "well-born". Kulika comes from the word Kula meaning "family" "tribe" "clan" "caste" "lineage" "good family" "chief" and the suffix -ika meaning "belonging to" "relating to" "related to" or "child of". There is some speculation that Kurikara came from kurika raja with the ra at the end being short for raja or "king". King Kulika or Dragon King Kulika was a son of Kadra.
 * The Kurikara-ken (倶利伽羅剣) is a famous sword in Japanese mythology being the name of the double-edged vajra sword of the Japanese Buddhist god of fire Fudō Myō-ō. It is depicted with a dragon coiled around it. The mythology is associated with Fudō Myō-ō's transformation into a fire-sword and consequently a fire-dragon in order to fight an enemy who also took those same forms.
 * The Kurikara-ken is usually depicted as a one-horned, flame-wreathed dragon coiled around and swallowing the tip of the upright vajra sword. This iconography is very popular and may also depict the god himself in which he is called as Kurikara Fudō. The kurikara engraving on the sword is similar to this iconography.
 * Coincidentally, there is a sword named Kurikaramaru (倶利伽羅丸) that appears in a kabuki play called Gion Sairei Shinkōki (The Gion Festival Chronicle of Faith) which is also related to the myth of Fudō Myō-ō.
 * Kōryū (紅龍 or 紅竜), more commonly known as Sekiryuu (赤竜) or Chilong (in chinese) is the "red dragon" or "vermillion dragon" in Japanese and Chinese mythology. It is a red-scaled fire-dragon who can breathe fire and is said to be born of the sun or from a volcano.
 * Similar to the named techniques of Inuyasha's sword, Kōryūha too has the kanji "破" meaning crush.
