Tatsuga is Ryu-kun's Sword. Its a blade created from the horns, fangs, claws, an scales of a great dragon lord. It is a heavy muscle sword only Ryu can use to its full potential. Tastuhime is Ryu-chan's Sword an Tatsuga's counter part. it was created when Ryu-kun an Ryu-chan split. Tatsuhime is a thin long sword an as powerful as her other half but Ryu-chan doesnt use her in battle.

I will have fuller details on these swords later.

(edit) Changed Tatsuga's design an added how long. will add more info later.
