Tira

How Tira joined the Tourney
Tira awaited outside the gates of the Lost Cathedral, languishing the outcome of the battle between Siegfried, who wielded SoulCalibur, and Nightmare, who wielded SoulEdge. When the swords clashed, Tira's mind was depleted, shattered into countless pieces by the destruction unleashed by the meeting of the swords. But somehow, she found an inner will, and clawed herself back to consciousness. And in the end, Tira had become two separate people. Her mind had reformed itself into the two entities that represented Tira's original, unstable personality.

Upon her return to Ostrheinsburg, Tira began processing the information that her watchers carried to her, and began manipulating numerous ways to give SoulEdge, her king and master, advantages in battle. She would use the inhabitants of the cursed city to wear down the power of the spirit sword. And at last when they fought, the cursed sword would turn Ostrheinsburg into a giant vessel and every soul within the place would be caught in its maw, including the spirit sword. She knew that then, her king would win.

Having kidnapped Pyrrha, who also took part at the Smash Bros. Tourney, Tira knew that her mother would seek to save her child and eventually met with Sophitia to reveal a shocking truth. Tira informed that her beloved daughter could not live without the evil influence of Soul Edge, and thus used her love for Pyrrha to pit Sophitia against any warrior who dared to confront the evil sword. Tira also manipulated Astaroth, convincing the latter to pursue the cursed blade in order to avenge his slain comrades, and the other to serve Nightmare. Along with these tricked souls, Tira additionally used Voldo's devotion for his master and convinced Cervantes to pursue Soul Edge as well.

Her plan was coming together. Tira had no doubt that SoulEdge would easily overcome the justice that was SoulCalibur with such rich souls at its hilt. Her king would consume everything! And at that moment, Tira too would become part of SoulEdge. A feeling she had never felt before swelled in her. But she, both of her, did not quite understand it. A tiny glimmer of fear sparked in the chink between her two personalities, but it was forced down below the surface of her consciousness. It would not emerge again. Despite this, Sebastian, Lili's butler, asked if he wanted to assist Tira, but she said "no" and before long, Tira joined the Tourney.

Ring Blade Toss (Neutral)
Tira throws Eiserne Drossel at her opponent like a boomerang.

Ring Blade Slash (Side)
Tira says "Swoosh!" in her Soul Calibur IV voice and slashes her Eiserne Drossel downwards.

Ring Blade Grappler (Up)
Eiserne Drossel grows to a longer height, allowing Tira to recover from an abyss in some stages.

Ring Blade Slide (Down)

Discord Parade (Hyper Smash)
Based on her Soul Calibur V Critical Edge, Tira will say "Alright..." and will proceed in dancing around with her Ring Blade — violently hitting the opponent while doing so. Each strike will make her weapon glow a golden orange and will produce small sparkles as the enemy endures more damage. When the maneuver is finished, Tira will say "Fall to PARTS!" in her Soul Calibur IV voice.

Judecca Requiem (Final Smash)
Based on her Soul Calibur IV Critical Finish, Tira says "Is that it?!" in her Soul Calibur IV voice and vertically slashes her opponent, leaps on top of them, and kisses them passionately while creating an explosion. Her opponent then screams in pain, in the same manner as if they were sent through a Star KO.

Depending on her opponent, this is what she'll say afterwards:

Doctor Doom/Alisa: NO WAY! (Soul Calibur IV voice)

Rocket Raccoon: I'LL CUT YOUR HEART OUT! (Soul Calibur III voice)

Ghost Rider: BREAK ALREADY! (Soul Calibur IV voice)

All Other Characters: There's no one else?!?! (Soul Calibur IV voice)
