Helen was Claymore No. 22 of the 135th generation in the Organization. Helen is often hot tempered and aggressive, humorous and rebellious at times who can appear to be a troublemaker, as Deneve notes. She seems to have a large appetite for a Claymore and can often be seen eating an apple. She is also the only Claymore seen eating and drinking for pleasure. "Helen" is a transliteration of the Japanese "Heren" (ヘレン, pronounced "he-ren").
