"By the way, what are these swords, Creige? They look really good." Kana asked. She had remembered Creige putting down three swords earlier. She knew who they were for but wanted to make it a surprise.
Luckily Creige understood what Kana was getting at by her words and smiled as he looked at the three girls. "You girls do not have weapons yet, so I made you some special swords with some of the rare materials found in the realm of gods. Each sword needs a drop of your blood to bind it to you. Once bound, it will turn into a ray of light and form a special sword tattoo on your hands. You can then summon it and de-summon it at will. Come let's get them bound to you first before I go over all its functions."
"Yay! Sword!" Rain and Angelica yelled out. Yana, on the other hand, was not as excited, but she was more of the bookworm type.
