- "Let's get serious... Arahabaki!!"
- — Natsu
What lies in her soul is Confidence.
In Soulcalibur V's promotional material, she is referred to as a Worthy Successor.
Despite her Asian name and origin, Natsu has tawny, ginger-blonde hair. She has a curious hairstyle consisting of multiple ponytails on the back of her head and she wears a shiny pink hair-clip decorated with feathers. Natsu wears a scarlet bodysuit with long sleeves and is protected by partial armor on her arms and hips. She has a liking to glittery pink items, as even her swords' handles are pink and their scabbards are decorated with pink stones. There is a red bandage tied around her right thigh and the feather motif is repeated on the back of her greaves. She has strings of shiny pink beads attached to her waist. Natsu's outfit is bird themed, possibly falcon, which is visible in the recurring feather ornaments and the decoration of her vambraces.
Due to Natsu only making a very brief appearance in the story of Soul Calibur V, there isn't much known about her, other than that she seems to be a spirited young girl.
Judging by her pre-battle and victory quotes Natsu is lazy and rather cocky. When looking at her face Natsu is shown smiling most of the time and she playfully laughs and chuckles when attacking, showing her playful and rambunctious side while also maintaining a serious fighting spirit.
Natsu is also rather stubborn and disobedient, as she would sometimes disregard and ignore the Fu-Ma clan's rules. However, she seems to listen to those whom she respects or cares for, like her master Taki. It is possible that her personality is affected by the spirit of Arahabaki.
Since Taki had often left the village to carry out missions, Natsu was raised as the adopted child of Chie. The gentle Chie was always there to heal Natsu's heart, injured by discrimination. Growing up with the stigma of being "possessed by an evil spirit." But she is gentle and a very kind person.
As a child Natsu was particularly shy, but she gradually grew up into a cheerful and lively girl after receiving Taki's teachings.
Natsu appears to pay attention to her appearance, characteristic of a girl of her age. Although she may be accostumed to the prejudice around her, she still seems to suffer from handling her unruly hair every morning.
Natsu was a member of the demon-fighting Fu-Ma clan. She grew up under the harsh glares of her fellow ninja, who feared the great demon Arahabaki that was sealed within her. Some even made attempts on her life.
Thankfully, Natsu's master, Taki, protected and supported her. The young ninja came to love and respect her mentor; though she often disregarded the clan's rules, Natsu always obeyed Taki.
But now it had been several months since Taki left on a mission to the western continent, and Natsu was growing uneasy.
"Master said her journey would last no longer than two weeks..."
It was then that a girl named Leixia appeared at the gates of the Fu-Ma village. She explained she was on an "adventure" to uncover the secrets of a mysterious pendant. When Leixia learned of the demon dwelling within Natsu, not only did she show no fear, but she was actually envious of Natsu. Drawn to the girl's cheerful innocence, Natsu offered to serve as her bodyguard. After all, the trip might provide an opportunity to find her missing master as well...
And so it was the two girls began their long journey west...
- Kuzukiri & Awayuuki
- Koringo & Himeringo
- Hunting Knife
- Kuzukiri & Mekki-Maru
- The Master (Natsu)
Natsu's fighting style is similar to Taki's but with a few changes. Her evade and counterattack patterns are more deceptive since she can disappear whilst evading. Her master's signature aerial throws are present as well, but they are more difficult to perform especially when using them to end a combo.
Great Curse of Arahabaki: Natsu will hold her kodachi in the air and exclaim "Lets get serious...Arahabaki!" She will then stick her kodachi into the ground as she summons the Great Demon, sending six wild blasts through the stage and the opponent high into the air. This Critical Edge is very effective as it leaves the enemy vulnerable to numerous air combos and can be used to finish or extend a combo. Additionally, Natsu can quickly shift into her "Possession" stance during this attack, which can cause danger to the opponent even if it is blocked. The downside to this Critical Edge, however, is that it can be easily evaded by the "Quick Step" tactic if the enemy is prepared, leaving Natsu open for attack.

- Arahabaki is, according to the Shin Megami Tensei Wiki: "An ancient Japanese aboriginal god since the Kohun period. The Momunofu were his servants and before his religion was submerged by the Shinto pantheon, Arahabaki was worshiped in Japan's North-Eastern regions. He was also worshiped by Nagasunehiko, an enemy of Emperor Jimmu, and so by the Emperor's orders Arahabaki became a symbol of treachery, rebellion, and heresy and his worship was forbidden for a long period afterwards. Nowadays, Arahabaki's clay figurine is especially common in inns throughout Japan." This demon is a recurring character in the Megami Tensei series, and is commonly a symbol for defiance.
- Many people in the community compare Natsu to the main character of the popular manga and anime Naruto, due to both of them being ninjas, having blonde hair, similar personalities and wearing very bright outfits. Naruto also had a demon sealed within him, just like Natsu. She also possesses the quote "Man... What a drag!", which is the catchphrase of Naruto character Shikamaru Nara. Another connection to Naruto is that she shares an English voice actress with Naruto's teammate and crush, Sakura Haruno, both characters being voiced by Kate Higgins.
- Her hairstyle might be a reference to the nine-tailed fox spirit, the Kitsune.
- Strangely enough, when she faces off against herself she will occasionally say "Foul demon...banish!". A quote that she uses to address an evil aligned character when attacking them. Because of this, she seems to be considered an evil character. Or at least considers herself to be. Despite her bubbly personality and allegience to the Fu-Ma clan.
- Natsu is the first Asian character to have light hair in her main design. This might have been caused by the fact that her hairstyle resembles that of Ayame from Tenchu, making the characters look very similar to each other if it weren't for the drastically different color schemes. During a livestream from Project Soul, the hair color was explained as a design choice to make her look as different from Taki as possible.
- Natsu's appearance is aesthically similar to the gyaru fashion trend in modern Japan; her decorated pink nails, light colored hair and flashy ornamentation are all typical of the style, including her thick, dark eyelashes and hair style.
- In her official 2D artwork, Natsu has glittery pink fake nails, but they're missing in her in-game model. She shares this discrepancy with Viola.
- Natsu's name shares the character 津 with Yan Wujin, the father of Leixia and Leixin. However, they are read differently from each other, due to vast differences in Japanese and Chinese reading.
- In Soulcalibur V, Natsu shares the bird theme of her outfit with Tira and Siegfried.
- Natsu's titles in Quick Battle are Phantom and Swift Sealing Knife.
- Natsu's theme—Faster Than A Howling Wind—bears a slight reassemblence to Taki's theme from Soulcalibur and Soulcalibur III—The Cursed Image. The rhythm is noticeably a lot faster, but it is played with a lot of the same instruments
- The title of Natsu's theme may be a reference to Fu-Rin-Ka-Zan (風森火山), a philosophy from Sun Tzu's book The Art of War. The characters translate into "wind", "forest", "fire", and "mountain", and is commonly translated as, "Be as quick as the wind, as still as the forest, as dangerous as fire, and as immovable as the mountains."
- In a behind-the-scenes video, the decision to include Natsu came from deciding that Taki would likely be too old to be a ninja anymore. In Odashima's mind, you can only be a ninja up to a certain age, after which you retire from active duty and focus on training younger ninjas. While Taki has retired, she's still watching over Natsu, he adds.
- A flower-like symbol can briefly be seen on Natsu's left shoulder during her Critical Edge and in one of her win animations. This could possibly be the seal placed on her or the symbol of Arahabaki.
- Though there's no connection between them, Natsu's personality strongly resembles that of Seong Mi-na.
- Some of Natsu's early costume concepts were based on shrine maiden outfits. Her other costume concepts bear references to geishas.
- In the concept sketches, it is suggested that Natsu's hairstyle is caused by the influence of Arahabaki.
- Natsu's alternate outfit resembles Setsuka's alternate outfit from Soulcalibur III.
- In Episode 15 for Soulcalibur V's story mode, Natsu uses Kuzukiri & Mekki-Maru.
- Natsu 1P in Soulcalibur V was designed by Tomoko Imura.
- Natsu is not a native of the Fu-ma village. Her own village was destroyed by Arahabaki when she was an infant.
- Natsu is the only character in the series to use a modern insult phrase, "That didn't suck." However, this remark awkwardly conflicts with the game's atmosphere, which is set up in the 17th century.
- Early beta versions of Soulcalibur V had a different theme for Natsu which was not included in the final version of the game.
- Natsu's weapons Kuzukiri & Awayuuki resemble Rekki-Maru & Mekki-Maru 1P appearance in SoulCalibur II , Which are Taki's primary weapons, this hints to their relationship as teacher and student.
- Every time Natsu uses some of her demon based powers, the seal placed on Arahabaki by Taki weakens.
- Natsu shares the same name with the main male protagonist of Fairy Tail, Natsu Dragneel
- Natsu is the only Japanese character with blonde hair. Setsuka also has blonde hair but her origin is unknown and she has black hair in Soulcalibur III.
Natsu (凪津) means "Calm Haven" in Japanese.
- Disciple of Taki.
- Friend, bodyguard, and travel companion of Leixia.
- Friend and travel companion with Maxi and Xiba.
- A demon known as Arahabaki is sealed within her.
