ESP Kenkyuukai (ESP研究会) is a Japanese group credited under both Roman letters and Japanese script, with the mixed-language official name helping the project stay identifiable in English- and Japanese-language listings.
The group is listed as being from Japan, and Haruka Kotoura (琴浦春香) appears as a member. That concrete lineup credit gives the entry a clearer identity than a purely descriptive profile and makes the name easier to place in artist searches.
