1. First Form: Winding Serpent (壱ノ型・委蛇, Ichi no kata: Ida)

Performs three rapid, forward slashes followed by a rotating slash that drives her opponent back. The final rotation is especially damaging and is ideal for countering larger demons.

2. Second Form: Venom Fangs (弐ノ型・毒牙, Ni no kata: Dokuga)

Assumes a defensive stance for three seconds, preparing a powerful counterattack. If struck during this period, retaliates with an overwhelming barrage of slashes from various angles.

3. Third Form: Coil Choke (参ノ型・塒締め, San no kata: Toguro Jime)

A massive spectral serpent coils around the target, immobilizing them while dealing ongoing damage, setting up the perfect finishing strike.

4. Fourth Form: Twin-Headed Reptile (肆ノ型・頸蛇双生, Shi no kata: Keija Sōsei)

Rushes forward, executing a powerful slash that closes the gap between her and her opponent, ideal for initiating combinations.

5. Fifth Form: Slithering Serpent (伍ノ型・蜿蜿長蛇, Go no kata: En'en Chōda)

After a brief pause, darts forward with blinding speed, delivering a lethal slash to end the fight in one powerful strike.

6. Sixth Form: Serpent's Mirage (陸ノ型・蛇影, Roku no kata: Jaei)

Creates several mirages of themselves to confuse the enemy, then attacks with unpredictable slashes from various angles.

7. Seventh Form: Venomous Rebirth (漆ノ型・毒生, Shichi no kata: Dokusei)

Channels energy into a single blow, striking with a venomous aura that poisons her enemy if the attack connects.

8. Eighth Form: Serpent's Embrace (捌ノ型・蛇抱, Hachi no kata: Jōyō)

Envelops the enemy with a spectral serpent that constricts and crushes them, dealing significant damage while immobilizing them for follow-up attacks.

9. Ninth Form: Serpent's Wrath (玖ノ型・蛇怒, Kyū no kata: Jadu)

Summons a colossal, spectral serpent that erupts from the ground to launch a powerful, sweeping attack, perfect for clearing out groups of foes or overwhelming large opponents.

10. Tenth Form: Eternal Serpent's Dance (拾ノ型・永蛇舞, Jū no kata: Ei Jabu)

The final form is an advanced technique that involves an intricate series of continuous, high-speed strikes that mimic the motion of a serpent's dance. This form is used for finishing powerful adversaries and is known for its unparalleled speed and precision. The flow is so seamless it becomes nearly impossible for the enemy to predict or counter.

(I added some additional forms to Serpent Breathing two are the ones Espeon made herself for her own oc in a different story)

Nichirin Blade: Her blade Isa shimmering teal, unlike her brother's purple blade. The blade is thin but exceptionally strong. The handle is wrapped in a fine-scaled leather dyed a darker teal and provides a firm grip it has golden accents that mirror a Serpent. The guard is circular with ornate carvings resembling coiling serpents and st the center is an emerald gemstone. The scabbard is polished wood with a lacquered midnight black finish adorned with intricate patterns of silver in the shape of serpent scales that wrap around it with a subtle line of teal pigment at the edge of the scabbard.

Kasugai Crow: Aina is a beautiful crow with black feathers and silver wings as well as pure white eyes. She was wearing a blue scarf around her neck.

Lover: Toshio Kanroji (Oc/ little brother of Mitsuri)
