Heart Kreuz (ハートクロイツ, Hāto Kuroitsu) is a popular clothing line for young girls that are featured in many of Hiro Mashima's creations. Elie loves this clothing so much that she wears it all the time. At some point in season 2, she addresses Heart Kreuz as the best clothing line in the world. Heart Kreuz symbols have found its way into many of the things and clothes in Rave Master, even men's clothing like Haru's jacket. Though Haru's clothing is constantly changing between long and short sleeves, there is always the cross-like sign on each side. It also appears to be the men's version of the brand look closely at the Rave that goes into Haru's sword, there is a small Heart Kreuz looking cross on it.
