the daytime, she a student and Nanase's senior at school. Admiring the abilities and wanting to freely use her own ability, she leaves a strictly disciplined student vigilante group, "EFG". This sensitive girl is common in these days. She has grown bored of her peaceful life as a student and kept searching for her "true self" for a long time. She keeps thinking that her powers as a "Fake Born" was what finding her true self meant. She walks under the night thinking that her powers should be used on other people. But people rumor that within the people who wander under the night, there's someone who takes a form of your "false self" from the time before you awakened as your "true self".

Phonon starts to hear rumors about the Hollow Night about two months before the actual story takes place. Her curiosity leads her to the check if the rumors are real. On a abandoned back alley, she enters the Hollow Night and is bitten by a Void. Phonon is frightened by the happening and runs away as fast as she can.

After Phonon has recovered and returns to school, she is approached by Tsurugi from another school. Tsurugi thinks that Phonon has become one of the In-Birth. He explains that based on the rumors from that certain night and the fact that she had to take leave from school for a few days. In exchange for a weapon and further explanation about the In-Birth, Phonon joins into EFG with the condition that their alliance is only temporary.

Phonon is great-looking character design... not too simple... but not "overly designed" either. She's a perfect fit for the series and fits the "moody and cool" overall vibe of UNIST. I love her default look with the striped leggings, and it's beyond awesome that the designers managed to incorporate a variety of leggings "styles" into her 2D sprite - including bare legs. That's clever sprite-work that you rarely see in video games anymore.

Phonon's appearance caught my attention when she debuted... but I didn't know was how much I'd enjoy her moveset! As an Ivy main in SoulCalibur, I immediately fell in love with Phonon's long-range keepaway fighting style. She has super-fun combos and amazing-looking animations all around. Phonon also has one of the longest-ranged low sweeps in the history of fighting games! ^o^
