I appreciate the addition of the party. I hope you don't mind a crossover, since we're apparently missing party members. So far we have a support tentacle tank, mob/dps ninjas, and a cumslinger red mage.

You are the offensive, front-lining futa knight that wields one of the strongest blades of the world: Ecchidna. Ecchidna can manifest as a spirit outside the blade and accompany you as your guide. She feeds on your sexual energy to maintain her form and power the blade.

As such, the blade conforms to your arousal levels. When your tremendous penis is at full mast, the sword becomes a massive, destructive greatsword. But when you're flaccid, it becomes a deadly combat knife the size of a letter opener. You must learn to control your emotions and time your arousal with your needs. Otherwise, you may also just learn to use different styles of combat based on the size.

Unfortunately, relying on your penis size means that outside factors can change how you fight. For instance, fighting in cold weather will force you to use the small weapon. Fighting in a river of sexy sirens will mean your greatsword becomes heavy and makes you sink.

Thankfully, you can somewhat control your arousal thanks to certain support that can give you a tentacled codpiece to stroke you hard member or even poke it down.

Because you're blade is generally fully erect due to the presence of your beautiful party, you have become known as a beast slayer.
