Tohka Yatogami

"You were there for me, you saved me, much like how today, you asked me out on a date and showed me how nice this world is."

- Tohka Yatogami, to Shido Itsuka

Tohka Yatogami is the lead female character of the Date A Live franchise. She is the first spirit to be saved by the franchise's main protagonist, Shido Itsuka.

Summary
When Tohka first appeared on Earth, on the 10th of April, she came under attack by the AST. That was also the same day Shido encountered Tohka and later discovered the real reason behind the spacequakes. The next time Tohka encountered Shido, she was again under attack by the AST. During Tohka and Shido's short conversation on their second encounter, Shido gave Tohka her name. During their third encounter in which they went out on a date, Tohka and Shido established a bond, as the boy explained to the Spirit that not all humans were like the AST who are out to kill her. It was during this time, after their date got interrupted by the AST, that Tohka had her powers sealed by kissing Shido for the first time.

After her powers were sealed, Tohka was still unstable and could go off at any moment, mainly due to her emotions which she didn't understand or know how to deal with. But, thanks to some consultation from Reine and some reassuring words from Shido, Tohka was able to better control her feelings of jealousy regarding Shido. After being sealed, Tohka started attending the same school, grade, and class as Shido thanks to the help of Ratatoskr. She made friends while at school, but at the same time, she still sees Origami as an enemy (in many ways), who was also at the same school and classroom as Shido and her. Tohka is currently living in an apartment complex made by Ratatoskr for Spirits beside the Itsuka residence where Shido lives.

Tohka was later captured by DEM at the end of Miku Lily. During the events of Miku Truth, when Shido came to rescue Tohka and was about to be killed by Ellen, Tohka became filled with such despair and transformed, attacking everyone in sight, including Shido. Westcott named her transformation the "Demon King," adding that this state was the actual form in which Spirits took on in the bordering dimension they had come from before manifesting in this world. Luckily, Tohka did not stay in her dark transformed state for long, as she was brought back to her senses with a kiss from Shido and saved once again.

Appearance
Tohka is a girl with dark-purple hair and pupils which are colored dark-blue on the top half and a mix of pink and pale yellow on the bottom half. Shido describes her as an "impossibly beautiful girl.”

Upon her arrival on Earth, she wore a dress with a black, cream, and pink color scheme and a set of purple-and-cream plated armor which adorned her shoulders and waist. The dress is open at the back and made up into a black corset (which exposes some of her cleavage) and a two-layered, knee-length skirt which has a pink-to-white gradient. Her hair is tied back using a butterfly-shaped hair accessory. She also wears a pair of gauntlets which have petal-like cuffs, both sharing the same color scheme as her attire, as well as a pair of armored boots.

Upon her admission to Raizen High School, she adopts the uniform of the said school, although she wears a skirt similar to the dress she wore upon her arrival.

Personality
When Tohka first appeared on Earth, unsealed, she was very wary of humans because she was constantly being attacked by the AST, before Shido finally got the chance to talk to her. However, after her powers were sealed by Shido, she could finally develop and express feelings, as well as experience life on Earth. Due to the fact that Tohka is new to everything (including her emotions), she has a very child-like personality that can make her seem naïve, emotional, energetic, and gullible at times.

Despite her lack of knowledge or experience, Tohka does have a normal sense of embarrassment, as shown by her overreacting when seen naked, or caught in otherwise embarrassing situations. At times, Tohka can be surprisingly insightful, as well as perceptive and understanding in regards to other people's feelings, especially when it concerns Shido and her fellow Spirits.

Spirit Form
Angel: Sandalphon

Weapon: Broadsword

Final Sword: Halvanhelev

Astral Dress: Adonai Melek

Tohka is a highly offensive combatant who uses a sword as her primary weapon. Aside from this, Tohka also has a lot of "mana" within her Spirit body, which increases both her offensive and defensive abilities. She can put up a powerful barrier around herself, utilize energy blasts with her hands or fingertips, as well as create shockwaves with a mere arm swipe.

Her primary armament is Sandalphon, which takes on the appearance of a gilded throne which doubles as the scabbard of her broadsword. Tohka's fighting style mostly consists of strong, swift physical attacks with “mana” encasement on her sword and body, or a high energy attack (like a laser beam) combined with her sword.

The throne itself seems to be a kind of support machine, depending on how Tohka uses it. The throne can be changed into a transport vessel by laying it horizontally, or to unlock the final form of her weapon, Halvanhelev, by cutting the throne in half, drastically increasing her Angel's destructive power. Later in the series, after Tohka's power was sealed by Shido, she can still retrieve a bit of her original power if she focuses hard enough and/or if she became emotional. Eventually, Tohka learns how to, albeit instinctively, take back the entirety of her powers, which she successfully does when battling Origami during the events of Tobiichi Angel (Volume 10).

Inverse Form
Demon King: Nehemah

Weapon: One edged sword

Final Sword: Paverschlev

Astral Dress: Unnamed

After prolonged exposure to negative emotions when Shido was about to be killed, Tohka transforms into her other form, which, according to Wescott, is her true form in the bordering dimension where she comes from. Tohka's overall abilities in this state are the same as in her Spirit form. She also obtains Nehemah, a darker version of Sandalphon, and her Astral Dress becomes much darker and more revealing. In this form, Tohka has no control over her body, attacking everything and everyone within sight. She also seems to gain an immunity to attacks used against her as she survived a point blank range attack Ellen used against her while in this form.

Tohka nearly entered this state again in Volume 10, when she was having a mental crisis because she lacked the power (due to being sealed) to protect her friends (the other sealed Spirits) against Origami's attacks. Fortunately, Tohka did not transform, as she instinctively realized beforehand that she was about to succumb to the dark power inside her again, knowing full well that relying on this power would not help her save anyone.

Trivia

 * Tohka's name reflects the naming pattern amongst Spirit characters. Tohka's name is written as 十香, with the character for "ten" composing her name. The "ten" in her name refers to the Tenth Sephira in the Tree of Life of Kabbalah, pertaining to "kingdom." The concept of "kingdom" is evident in her attire, which is a mix between the dress of a princess and the armor of a knight, and her weapon, which comes in the form of a throne.
 * Her Inverse Angel Nehemah is tenth in the Qliphoth which also corresponds to her number.
 * Her angel's name (Sandalphon) was translated variously as 'Lord of extent of height", "Co-brother" and "the sound of sandals."
 * According to the afterwards of Volume 7, the reason for Tohka's inverse form having a more revealing design stems from the idea that an evil character is more prone to seducing the hero of a story, while if she was trying to be nice and hide her identity she'd behave more modestly to mask her true nature.
