Koukaku

A koukaku kagune (甲赫, kōkaku, "shell-red") is released below the shoulder blade. Due to its high density of RC cells, it is heavy and extremely robust, giving it the greatest sturdiness and making them very well suited for defense. Normally, they are shaped into armors or shields, but on the offense, they can be shaped like melee weapons such as drills, hammers, blades, and swords. Koukakus tend to have issues with speed, due to the extreme density of their kagune. Note: the loss of speed applies only when the koukaku is manifested.

**1000+ RC**

One kagune, barely the length of your arm. You may choose the form it takes (distinctive blade, shield, warhammer etc.), however, it cannot be altered after. Your movements are sluggish when the kagune is deployed, however, it carries a certain density that allows you sufficient defense.

**2000+ RC**

One kagune, several inches longer than the length of your arm. You've grown used to the weight of your kagune, and can maneuver it with confidence, however you are still on the slower side and can be thrown off-balance. It is capable of withstanding the blows of several fatal attacks within reason. You can cut through just about anything, and have the potential to damage/slice off stronger opponents' kagune/quinque within reason. You are able to deliver powerful strikes that are enough to stun opponents, and have superior defense.

**3500+ RC:**

One kagune, about an arm and a half long. You are able to attack with calm, precise movements, or a series of well-aimed speedy jabs if necessary. Your mobility increases, and you are able to temporarily stretch or slightly morph the shape of your kagune (bending it a little, elongating it slightly, etc.) Your kagune is extremely difficult to damage or break, earning you a reliable and trusty weapon and shield. Also... lugging around such a heavy weapon that's literally attached to you... you're super physically strong! (Well... alarmingly stronger than most of your rating, anyway.)

**5000+ RC**

Two large kagunes, you may also choose the shape of the second kagune (does not have to be the same as your first), and you are able to stretch them for longer durations when needed. You are alarmingly fast for a koukaku, and are capable of tanking multiple blows before falling. Your kagunes are essentially unbreakable now, and you make for a tough nut to crack, with your advanced speed and no glaring weakness. A direct hit from your trusty kagune is enough to stun opponents completely, if not completely knock them unconscious.

**10,000+ RC**

Two large, hulking kagunes. You are able to modify your kagunes to a degree when needed (e.g. growing stationary spikes on surfaces) and you've essentially overcome all issues with speed, able to be on par with most ghouls. While you may never be the fastest, who cares about a few scratches when you've got your extreme durability? You hit like a derailed train spiraling off the side of a cliff (essentially, very very hard) and are capable of tanking as much damage. The thought of anything being able to make even a dent in your kagune is hilarious.

**17,000+ RC**

Two giant kagunes. You are able to stretch your kagune to a reasonable extent and alter the appearance within reason with ease, complete with things such as functioning drills, etc. Anyone who dares call you "slow" will end up with a skewered throat before they manage to finish such an insulting sentence (essentially... you're speedy). You're pretty much invincible, a powerhouse of a ghoul with both elevated body strength, and arguably the strongest weapon known in history. In a (very hard) nutshell, Thor's hammer has got nothing on you.
