Heart Kreuz Armor is an armor made by the Heart Kreuz fashion company.
Throughout the Fairy Tail series, there are currently three models of the Heart Kreuz Armor available.
The first armor consists of a metal breastplate, with a high armored collar and plated shoulderguards with each side being composed of four plates. On the breastplate's left side is the symbol of the Heart Kreuz fashion company: a cross with the edge pointing downwards, having the shape of a heart, and donning the brand's name over the cross's right edge. In addition, the armor's waist guard is composed of three plates, each held up by a simple belt.
Her second model of the armor is more detailed, sporting a breastplate now composed of a single piece of metal, decorated with curved lines and a deformed version of Heart Kreuz's mark. The right arm of the mark's cross extends to armor's right side, with the mark of Fairy Tail added under the cross itself, which is now lacking the brand's name. The shoulderguards are also larger and more detailed. The waistguard is now composed of only two elaborated plates hanging from a simple belt over a smaller thinner pair of plates circling her waist. The most visible additions of the new armor are the plated gauntlets extending up to the wearer's elbows, which are covered by elbow guards adorned by protruding metal ornaments reminiscent of feathers, and a prominent armored collar circling their and leaving the front side open. This is made up by protrusions similar to the ones on the wearer's elbows. There is a variation of this particular armor which involves line-less shoulderguards and a lack of metal feather-like protrusions on the collar.
In the year X791, there is a newer model of the armor. This one has rounded single-piece pauldrons with a breastplate and fused collar featuring a large Heart Kreuz cross centered on the chest. The wearer's gauntlets also omit the previous version's feathery elbow guards in favor of curved plate. Unlike both prior versions, the front and back torso plates do not meet, leaving the wearer's sides exposed. Finally, the waist armor features a single plate overlapping the chest piece. A variation of this model involves the waist armor adding a V-shaped piece that circles the hips instead.
