"Might as well use this awakened manga
hero power to its fullest. No use wasting
something so cool, right?"

Phonon (フォノン) is an unallied In-Birth who has recently awakened to her powers. She is a third-year middle school student and an aspiring writer who admires all kinds of supernatural things. "Phonon", the name she uses in the current day for herself, was originally a pen name she used in her younger days, believing it to be the true name of her soul.

In the Hollow Night, she wields the Void Fragment Muniel as a whip.

She first made her debut in the arcade launch of UNDER NIGHT IN-BIRTH Exe:Latest.

Background

Adrift in a world of mystery, the "Chemeti"

UNDER NIGHT IN-BIRTH

Having a strong admiration of power, Phonon leaves the EFG, a student self-defense force known for their strict rules, so she can use her powers more freely. Her behavior is not unlike a normal student's, going through a sensitive stage and wanting to find their "true self" amid the exhaustion of daily life. She believes her In-Birth powers are proof of awakening to her true self. As such, she uses her power against others under the darkness of night. Little does she know that there is someone else who also moves shadows who knows her "false self" from before she awoke.

UNDER NIGHT IN-BIRTH II [Sys:Celes]

Drunk on visions of comic book superheroics after acquiring a powerful EXS, Phonon frolicked along in the Night.

Her high spirits gave her the momentum she needed to defeat the evil boss--in turn boosting her confidence and pushing her even further. That's when the foul Re-Birth appeared, plotting his Immortalize--his plan to bring the world to an end by flooding it with Voids. But Phonon greeted the catastrophe with a smile: ""Now THAT'S what I'm talking about!"" Ignoring her orders from the EFG, Phonon throws herself into the Night.

"I never played well with others anyway!"

Appearance

Phonon is a slim, young girl with green hair and darker green eyes. Her attire consists of a grey, two piece waistcoat, with a pink, long-sleeve dress with black streaks around the bottom and middle sections. The bottom of the dress is adorned with small, black frills. Her legwear consists of a pair of black and white striped leggings and a pair of black stilettos. She also wears a pair of red headphones to stop her from harming herself with her own powers.

Her school uniform is almost identical to one worn at the school she and Nanase go to, down to the green shirt, short skirt and cravat, which she wears more loosely. A big difference is that she wears a light grey, unbuttoned blazer over the shirt with black rimmed lapels. In addition to that, Phonon wears a pair of completely black leggings.

Phonon's original hair color was black, but it was dyed green before the main story.

When trying to hide her identity from Nanase, Phonon donned an incredibly paper-thin disguise consisting of a black opera mask for her and a pink ribbon and lipstick for Muniel.

Personality

Most of the time, Phonon seems to be very wise-cracking and is quick to look down on other people through a harsh and demeaning front. However, she is deeply obsessed with supernatural phenomena and willingly risked her life to become an In-Birth. During the Hollow Night, she puts on a more haughty act befitting of someone of a higher status and power than her own, which has lead to awkward situations.

Phonon is also a very bad liar, as Tsurugi was able to completely see through her act even if he didn't do any research beforehand. She also tends to be very easily sensitive towards her real name or anything to do with her mundane life, as well as having a one-sided vitriolic dynamic towards Nanase even if the very latter is genuinely acting nice towards Phonon; despite this Nanase easily angers her whenever she speaks out her original name.

Story

In grade school, Phonon was good friends with Nanase, due to them originally having very similar interests. However, their friendship started to grow distant when Phonon moved to middle school, with Nanase moving to a different school a year later.^{[citation needed]}

Scenario: A False Identity, A True Self (偽りの身分、本当の自分)
About two months before the actual story takes place, Phonon starts to hear rumors about the Hollow Night and the "shadows" that grant people mystical powers. Her curiosity leads her to the check if the rumors are real by listening in on conversations between other students during school hours, though an emergency assembly regarding the ongoing rumors and warning students about wandering alone at night interferes with her schedule.

After school, Phonon heads out into city during dark hours to search for the rumored shadows in a nearby park, but the unsettling atmosphere and darkness cause her to give up and head home through the shopping district. While there, Phonon overhears a group of female students talking about how a second-year student got attacked near a shrine, reinvigorating her.

Phonon goes to look for the shrine, but ends up getting lost in an abandoned back alley. While trying to find her way out, she gets hit with a sudden feeling of nausea and realizes that she has entered the Hollow Night. Shortly after entering the Night, Phonon is discovered and is bitten by a Void despite her attempts to escape, though she is soon able to break free from the Void's grasp and runs away as fast as she can, barely escaping with her life. Phonon makes it back to the shopping district and is asked as to what happened by a concerned woman, but Phonon simply brushes it off as being attacked by a large dog. Once the woman leaves, Phonon finally decides to head back home but ends up collapsing from fatigue.

Two days later, Phonon tries to head back to school after being called in for questioning, but her mother tries to send her back to bed; Phonon, however, manages to convince her mother to let her go in for questioning on the afternoon. After being questioned by staff, she heads home. The next day, Phonon has fully recovered and spends the majority of her day back at school. After school, Phonon ponders whether to head back to the Hollow Night or not, but eventually decides against it.

While walking towards the school gates, Phonon is approached by two people from another school named Tsurugi and Komatsu. Tsurugi deducts that Phonon has become an In-Birth after looking through the attendance records for her school and manages to see through the lies she comes up with. Soon, Phonon cracks and admits to wandering into the Hollow Night. Tsurugi offers her to come with him and Komatsu to their headquarters at their own school, to which Phonon begrudgingly accepts.

When they arrive at the school's Student Council headquarters, Tsurugi and Komatsu explain that they are members of the EFG, a vigilante organization that consists of school students who have become In-Births after wondering into the Hollow Night. Tsurugi also explains the basics of the Hollow Night and how EXS works to Phonon, who's only really interested in her powers. Seeing how excited she is, Tsurugi offers her a weapon in exchange for her services in the EFG; A shape-shifting Void fragment called Meuniel, which transforms into a whip for Phonon. Phonon gladly accepts the weapon, but has to be stopped by Tsurugi after getting too over her head with her new weapon while in the EFG headquarters.

Tsurugi then explains to Phonon that EFG has very strict guidelines when it comes to students using their powers within the organization. Students are not allowed to use their powers unless it is specifically needed, and that abusing their powers will result in them being classed as an enemy by the EFG. Despite these guidelines, Phonon begrudgingly acceps and joins the EFG, but secretly plans to leave once she has learned the ropes of her abilities and the Night. Outside of the school, Phonon parts with Tsurugi and Komatsu, promising to master her powers. A month later, she leaves the EFG.

Arcade Mode (アーケードモード)
A month after Phonon leaves the EFG, she decides to head out into the Hollow Night to test out her powers after narrowly escaping some fellow In-Births.

During her ventures into the Hollow Night, Phonon comes across Hyde, who tries to strike up a conversation regarding their specific weapons and the history of them. However, Hyde's happy-go-lucky nature when talking about Meuniel causes Phonon to lash out in frustration, starting the fight between the two, to which Phonon emerges the victor.

Later on, Phonon comes across Gordeau, who at first mistakes her for Licht Kreis' Crimson Knight, but quickly gets over it when he sees that Phonon's harsh, dominating behavior is an act. Gordeau likens Phonon's harsh demeanor to Hilda, but quickly backpedals on his statement when Phonon takes an interest in meeting her. Despite Gordeau's attempts to convince Phonon to give up the act, she ends up challenging him to a fight in order to figure out the location of Hilda. The two fight, with Phonon emerging victorious.

Phonon finally makes her way to the Altar of Light and Darkness, where she meets Hilda. Phonon tries to put on her domineering persona, but ends up enraging Hilda by calling her old, causing her to attack Phonon. Hilda soon calms down, however, and begins talking to Phonon about her past with EFG, though she simply brushes them off as "goodie-two-shoes". Intrigued by Phonon's attitude towards the faction she worked for, Hilda challenges her to a fight.

As soon after Phonon defeats Hilda, Nanase barges into the Altar, demanding a fight with Paradox. Nanase ends up spotting her childhood friend, calling out to her by her real name. This ends up scaring Phonon, who doesn't recognise Nanase at first due to her having a more feminine look. Nanase's repeated use of Phonon's real name starts to anger the Chemeti, and it isn't long until she reaches her breaking point and threatens to erase all of Nanase's memories of her.

After a brief scuffle, Phonon is able to knock Nanase unconscious and carries her out of the Altar to somewhere safe. In order to keep Nanase from recognizing her, Phonon dons herself with a paper-thin disguise. Nanase wakes up, believing that Hyde attacked her, but is unable to remember much else, much to Phonon's glee. Nanase thanks Phonon for her supposed help before heading back on her way. Finally alone, Phonon expresses her satisfaction with the results of her powers, but notes to be wary of Tsurugi and the rest of EFG. Meanwhile, Nanase watches Phonon from a distance, revealing to have faked her memory loss.
