**Sayo Hikawa** is a character from BanG Dream, who is a third-year student at Hanasakigawa Girls' High School and the guitarist of Roselia, who debuted in WPSA: BanG Dream! series, and is one of the two overarching antagonists in the WPSA: BanG Dream! series, particularly the final chapter. She is a member of both the student council and disciplinary committee. She is the older and more serious twin of Hina Hikawa.

## Appearance

In her normal form, Sayo has slanted green eyes and long, light, teal hair about navel length with her forelocks worn behind the ear with a curl on the end. Her bangs are neatly parted with the exception of a single loose lock. Her casual attire is simple with a tomboyish, yet cute tone, mixing pale and dark shades.

In her angelic form, Sayo's hair becomes a blue-ice colour, and her eyes turn to blue. She has icy wings behind her back.

## Personality

A serious and fussy girl, Sayo is somewhat cold in nature, even towards those she is close to. She never cuts corners or accepts shoddy workmanship, and is far too serious for her own good. She tends to stubbornly deny liking or being fond of certain things, such as fluffy animals or french fries.

In comparison to her sister Hina, Sayo is fairly stiff and sharp, and is highly stubborn when trying to do what she believes is best for others. She is very formal, and addresses most people by their last names, except for her sister, Tomoe, Haruhi, Trevor Philips (whom she is deeply acquainted with), Riko, Reg, Nanachi, and both her cousins Alice and Eve Kagayaki. Like Yukina, she is prone to make snide or rude remarks, though often these remarks do not reflect how she actually feels.

In the WPSA stories, when firstly encountered by the WPSA in her angelic form, Sayo develops a psychotic and destructive personality, with a fixation of world destruction, stemming it from the extremist ideals of the militaristic doomsday cult Angels of the Apocalypse to destroy every living thing on Earth and renew it.

## Powers and Abilities

By the final chapter of WPSA: BanG Dream's series finale, Sayo Hikawa, along with her twin Hina, is awakened as one of the Twin Angels of the Apocalypse, being the Ice Angel, which grants her the powers of ice. Sayo's guitar can transform into an ice scythe, known as Malum Necessarius, while in her own angelic form. She was considerably powerful, who was able to overpower a group of WPSA members during their final battle, including the Shining Chiyu Tamade. After being defeated, Sayo's angelic form becomes weakened but controllable, with her being able to use it in her own will.

Unlike Hina who relies solely on brute strength through her mallet Judicium, Sayo utilizes an array of cryogenic powers from her scythe.

* **Cryokinesis** - Being an ice angel, Sayo utilizes the powers of ice, allowing her to manipulate it under her whim. Her source of power comes from her scythe, known as Malum Necessarius, which is a scythe that transforms from her guitar.
	+ **Icicle Touch** - Sayo's powers are bolstered significantly by the powers of ice, but at the cost of weakening her defenses.
	+ **Ymir's Fist** - Sayo's left fist transforms into ice, allowing her to unleash a damaging hook towards the opponent.
	+ **Arctic Surge** - Sayo is capable of freezing an entire area up to -20°C.
	+ **Icicle Edge** - Slamming the Malum Necessarius into the ground, Sayo unleashes an array of smaller ice spikes in a line, followed by two bigger ice spikes.
* **Flight** - Sayo has ice wings on her back, which gives her the ability to fly, but only if she is transformed.
* **Teleportation** - In Ice Angel form Sayo is capable of dashing at high speeds. Demonstrated when she was able to subdue Chiyu Tamade before she used her Shining powers with a blow to her face.
* **Self-Upgrading** - Sayo's weapon can transform into a two-bladed ice scythe, greatly increasing her fighting capabilities.
* **Marksmanship** - Being a member of Haneoka's Archery Club, Sayo is proficient in archery and is able to utilize the usage of bows and arrows. However, her peak accuracy is later demonstrated in her angelic form, when she fires a volley of ice arrows towards her targets.

## Relationships

### Alice Kagayaki

Alice, unlike Eve, did not interact much with Sayo until in Chapter 40 in WPSA: Kiratto Pri☆chan Season 3. Much like in the canon, prior to Chapter 40, the revelation behind Alice being the older twin to Eve is not revealed. Later on, after reuniting Alice to the Kagayaki family, the family reunion between Sayo's family and their family was only met with antagonism. This was after it was revealed that Sayo and Hina's father was the older brother of Alice and Eve's mother, who became divided for years after a tragic accident killed their grandparents (Sayo and Hina's father and Alice and Eve's mother).

With the assistance of the WPSA, it is now finally fixed, as Sayo and Hina's father and aunt have finally come to terms about the tragedy that once befall both of them, following it up with a reconciliation.

### Eve Kagayaki

Sayo and Eve started interacting in Chapter 28, but it was initially not in good terms, because of a familial feud between Sayo's family and her family. Later on, after reuniting Alice to the Kagayaki family, the family reunion between Sayo's family and their family was only met with antagonism. This was after it was revealed that Sayo and Hina's father was the older brother of Alice and Eve's mother, who became divided for years after a tragic accident killed their grandparents (Sayo and Hina's father and Alice and Eve's mother).

With the assistance of the WPSA, it is now finally fixed, as Sayo and Hina's father and aunt have finally come to terms about the tragedy that once befall both of them and caused a divide, following it up with a reconciliation.
