Rose Knights

The Rose Knights *(バラ騎士, Bara Kishi*) is Grim's selected 13 he trusted to the last of his power during the First War with Spirit. Grim traveled the lands to find the most powerful knights and mages he could find who had a pureness of heart to call his Rose Knights - serving as his generals against the war against Spirit and his great army.
Grim's Knights were loyal, undying, and most of all - his greatest friends. He treasured each unique knight on their own leisure and thought greatly of all 13 equally. Grim gave the last of his power to ensure the lives of his Knights and to ensure his own victory.
For Grim, the beauty of this flower expresses promise, hope, and new beginnings. It is contrasted by thorns symbolizing defense, loss, and thoughtlessness, but at the center of the Roses, there needed to be a catalyst of sorts - a Sun for the Knights that whom is full of bravery, the "*Seiheiki*". The Seiheiki of that millennium who Grim met during his travels in search of the Rose Knights.
Unfortunately, however, during the First War, the first age of Roses could not defeat Spirits army - all of them passing away in the process. Though, they did suppress his army of the undead and Spirit himself for him to return to Io, in wait of the next Seiheiki after killing the First Seihei.
The current Knights are the previous ages reincarnation, whom also happened to share the same lineage and true of heart.

Bond
In order to fully gain the powers that the Seiheiki possesses, the Knight be one of righteousness, prowess, wisdom, morality, and genuineness of spirit. The Knight must also reciprocate the Seiheiki's affection back towards the Knight, seeing how one's love and affection is truly the greatest source of one's power. Seeing how the Seiheiki gathers their magic from the Celestial Force itself, the Seiheiki is able to disturb the Spirit Energy from it to give to the Knight in need.
The first level of the bond is whenever the Seiheiki and Knight happen to be in the same area with one another. In which, the Seiheiki will get the mark of the Rose, while the Rose Knight gets a sharp "sting of pain", alarming them that the Seiheiki is near. It isn't until the true bonding between the Seiheiki and Rose is fulfilled until the Rose manages to kiss the Seiheiki.
A kiss because it represents sentiments of love, passion, romance, sexual attraction, sexual activity, sexual arousal, affection, respect, greeting, friendship, peace, and good luck, among many others. In some situations, a kiss is a ritual, formal or symbolic gesture indicating devotion, respect, or sacrament.
The Rose Knight most also recite the pack - that comes free of will to the Knight, which unites both his and the Seiheiki's Spirit Energy so he may possess the small energy he receives from the Celestial Force,"

*Let it be declared now;my flesh shall serve under you, and your fate shall be with my sword.**I submit to the beckoning of the Seiheiki.***
**An oath shall be sworn here.I shall attain all virtues of all of Heaven;I shall have dominion over all evils of all of Hell.I shall wield your chains, and be your shield**
***I will be you're Knight, and you, my Princess***
***I will protect you until my dying breath, as you will protect me***
'''***Answer**, if you would submit to this will and this truth."*
