During the Septentrione campaign, Io first approaches Daichi and the protagonist at Shibuya Station after noticing their uniforms are from the same school as hers. In contrast, at the start of the Triangulum campaign, Io, Daichi, and the protagonist have been friends for a while and already have a close bond with each other.[4]
Io is initially mild-mannered, dislikes interpersonal conflict, and has trouble asserting herself, but also possesses strong mental fortitude and an inquisitive nature. She strongly values her family and friends and is willing to risk her life to protect them if needed.[5] After interacting with the protagonist, Airi Ban, and Hinako Kujou, she grows more bold after understanding the values of speaking her mind.[6]
During the Septentrione arc, due to her dislike of conflict, Io will often apologize to try and disarm situations even if the other party is being rude or at fault.[7] She adapts to the realities of the invasion far quicker than Daichi does, taking events at face value while seeking out answers to unknowns. Many of her Fate episodes revolve around finding answers to her questions, such as how the Demon Summoning Program and Terminal systems operate.[8] She also develops a crush on the protagonist, which Airi and Hinako tease her about.[9]
During the Triangulum arc, Io is more bold and hesitates far less when speaking. Many of her interactions concern her helping others who are alone or isolated. Io openly worries about Miyako Hotsuin and directly voices opposition to her utilitarian mindset, and her Fate episodes involve her helping a woman who lost her family to support her in the same way the protagonist helped her.[10] In addition, she values the safety of her friends and family even more in the Triangulum arc, as she now knows how it feels to lose them. This concern can even come across as pushy, seen in her worries over the protagonist's condition after fighting Spica and in her attempts to befriend Miyako at the end of the week.
Gameplay
Io is a mixed attacker with high strength and magic stats, favoring magic slightly more, but lower vitality and speed. She can be flexibly used as either a physical or magic attacker, or both, depending on the needs of the map. However, she may struggle to keep up as allies like Airi or Jungo Torii join with more specialized stat spreads.
As the player gains access to better physical skills, her low vitality and speed stats hinder her use as a physical attacker due to many skills scaling off of vitality or speed. With that said, her higher magic and MP pool allow her to run physical demons more safely than physical-only teams, as she can quickly patch up her demon allies with recovery-based Auto Skills or strong recovery spells like Prayer or Samarecarm. She can also utilize stronger magic skills better than fellow mixed-attacker Makoto Sako, who instead favors strength over magic.

Septentrione Arc
- Main section: Devil Survivor 2 § Synopsis
On Sunday, Io approaches Daichi and the protagonist at a platform in Shibuya Station to ask them questions about their practice exams. Not long after, the three are nearly killed by a train accident at the station platform, caused by the earthquakes and calamities brought forth by the Septentriones. They are able to survive thanks to Nicaea, forming contracts with demons in the process.
As the trio wanders the city to gather information about the crisis and help Io find a way home to Ariake,[a] she notices various irregularities between the current crisis and a comparatively normal natural disaster. After some time, Dubhe appears and Daichi is separated from the group in the ensuing chaos. Io and the protagonist receive his death video, and Io pieces together that while the events in death videos can be prevented, the victims are not alerted to their own deaths. They rush to save their friend, succeeding with help from Makoto.
Makoto introduces the team to Yamato Hotsuin and treats Io's sprained ankle from the battle to save Daichi. Not soon after, Daichi and the protagonist overhear Yamato ordering Makoto to arrest them, so the three decide to escape from JP's. Later, the team run into Dubhe again, though this time they defeat it. Yamato appears once more, commending the party for their efforts and thanking them for defeating Dubhe. He lets them join JP's, allowing the party to obtain food, shelter, and information about the disaster in exchange for helping the organization to defeat the Septentriones.
On Monday morning, Io learns her home has been destroyed, and her parents' whereabouts unknown. Later, in Osaka, Io is struck by the amount of damage the Septentriones have caused, and realizes the crisis will not resolve itself.[11] Later, after defeating Merak, Hinako helps Io and the protagonist realize the Septentriones share names with the stars that make up Ursa Major.
On Tuesday morning, while helping JP's agents tend to wounded civilians, Io recognizes her mother being carried in. Her mother, gravely injured, tells a tearful Io that her father has already died before passing on herself. Though devastated by this news and the shock of watching her mother die before her, Io joins the party in going to Nagoya, concerned about Daichi who has gone missing there. Some time later, the party receive Jungo's death video, which also shows Daichi being held hostage at the Fushimi Science Museum. As the party plan the rescue operation, Io volunteers her plan, "Operation: Cardboard Box",[12] which succeeds in rescuing Daichi.
On Friday, Yamato unveils his gambit to defeat Mizar, part of which requires the demon Lugh. He explains Lugh's power has been fractured due to the Void and requires a human medium to manifest it at the risk of their life. Io is revealed to be the only one physically capable of channeling Lugh. After learning this, she runs away, and the other tamers receive her death video depicting her collapsing after channeling Lugh. If the protagonist chooses to talk to Io afterwards during the event "Io's Resolve," she confesses how afraid she is to die and her disbelief in being the only candidate for the ritual. However, thanks to the protagonist's encouragement, she can steel her will to survive the process.
Io's survival depends on how high her Fate is with the protagonist. If her Fate is at Stage 4, she will always survive. Completing the optional event "Io's Resolve" will decrease the points needed for her survival and allow her to survive if her Fate is at Stage 3 or half-way through Stage 2.[13][b]
Once preparations are complete for the channeling ritual, Io is able to successfully wield Lugh's power to unleash the Dragon Stream, which proceeds to devour and cripple Mizar. Io then falls unconscious. If Io's Fate is high enough, she will wake up not long after. If she dies, Daichi, Airi, Joe, Hinako, and the protagonist will mourn her death before going to defeat Mizar for good.
After defeating Mizar, Io joins Daichi's faction in hopes of stopping the fighting between friends. If the protagonist decides to side with someone other than Daichi, Io can be recruited if her Fate is at Stage 4 or higher after the protagonist explains his reasons for his decision.
At the end of Daichi's Triumphant route, while Polaris restores the world, Io will reflect on how close she and the protagonist have grown over the past eight days and vows to remember him even after the world's regression. In the restored world, she, Daichi, and the protagonist meet again at the Shibuya Station platform just like at the start of the game, but instead of the train crash interrupting their conversation, they make plans to hang out. The trio is then seen walking out of the station to a peaceful Tokyo.

Trivia
Nomenclature
Like most characters in Devil Survivor 2, Io's name is based on her zodiac sign, Taurus. Her first name is a direct reference to Io, a woman from Greek mythology who was turned into a cow by Zeus and whose myth may have ties to the origins of the Taurus zodiac sign.[16]
The kanji in her name literally translates to "new rice field" (新田 / "nitta", lit. "new" and "rice field") and "string-fastened beginning" or "held-together mentality" (維緒 / "io", lit. "hold together (with rope)"[17] and "beginning" or "mental state"[18]).

Notes
- ↑ Ariake is around 13km or 8 miles from Shibuya by car. It is located near Odaiba on one of the manmade islands in Tokyo Bay, and would take around 2.5-3+ hours to walk to from Shibuya Station.
- ↑ Specific values: Fate 2 is reached at 102 points, Fate 3 at 134 points, and Fate 4 at 199 points.[14] She needs at least 190 points to survive normally, or 110 points to survive if the event "Io's Resolve" is triggered.[13]

Affection points cannot be viewed in game, but you can assume if Io's Fate is at Stage 4 then she is guaranteed to survive. Furthermore, if you have triggered [REQ 6-16] [※corresponds to the "Io's Resolve" event] and her friendship points are 110 or above, her death can be avoided.
