Nanabi is the seven-tailed kitsune, making her the third strongest member of the kitsune race.
She was first found by Luka in the Cave of Treasures, along with a Tamamo copied from a parallel world by White Rabbit. Of course, Nanabi thought she was the real Tamamo, and when she found out it wasn't, she was disappointed in herself for being tricked so easily.
She is first encountered by Luka in the Cave of Treasures.
When Luka arrives to collect Poseidon's Bell, she refuses to let him through, as Tamamo is in there. Luka tries to reason with her that they just want Poseidon's Bell, but she won't have it.
They forced to fight Nanabi, and the fight is going in her favour. However, their fight is interrupted by Alice the XVII, who was observing the fight the whole time. Nanabi is just as surprised to see her as Luka is, and prepares to attack her. But the 17th follows up with Vaporizing Rebellion Sword, depleting her health pool to zero instantly.
Nanabi loses the will to fight, and Tamamo comes out to seemingly investigate the commotion, but she starts reenacting the events of the original trilogy instead. She thinks Luka sealed Nanabi alone and treats everyone else as if they aren't even there. Alice XVII explains to Luka that this is not the Tamamo of this universe. Rather, she was copied and pasted from another world by a particular rabbit, but this Tamamo is no less powerful than the original one. The reason behind a Tamamo being here was to prevent Luka from getting Poseidon's Bell in the fundamental reality, by setting Nanabi to guard it. And the reason behind a Tamamo being here to do that is to keep this world as close to the authentic one as possible.
Shortly after this revelation, White Rabbit senses something is amiss and appears in Tamamo's place to investigate.
She notices the 17th and realises it must have been her who told Luka about this Tamamo being a fake, much to her disappointment, as it was working well until Neris showed up. Because of all of the trouble Neris has been causing the White Rabbit recently, she stops time and prepares to erase Neris.
But Nero materialises behind the White Rabbit while time is still stopped, and whacks her with Flash Kill before she can react, dazing her. White Rabbit is confused that Nero could do that, as time should be stopped. He mocks her for thinking she is the only one who can control time, and teleports elsewhere, along with White Rabbit. Naturally, no one else saw that, as time was stopped. To them, White Rabbit vanished on the spot. But Neris knows what happened.
Once time returns to normal, the first thing Neris asks Luka is if they can go on a date.
Ilias answers for him and says no.
Neris prepares to take her leave, but she mentions to Luka that she won't take no for an answer next time and vanishes.
Nanabi is upset that she was so easily deceived by a fake Tamamo, and believes that the real one won't want to see her again. Nanabi decides to spend a while training in the cave alone until she believes she can show her face to Tamamo again.
Luka can challenge her, and Nanabi will join him on his adventure in exchange, but it is a tough fight.
"A senior member of the Kitsune race and fiercely loyal to it's Queen, Tamamo. Though she can eat anything, she prefers semen above anything else. Using all seven of her tails, she holds down the male as she forces him to ejaculate. In addition, she is able to turn her tails into semen-sucking tentacles, sucking in the male's penis and using them to milk the man. Though she normally just feeds, if she finds a male she likes, she will make him her mating partner. Using her amazing vagina, she will force the male to mate with her continually until she conceives."

She is the easiest of the super bosses but is still difficult to defeat. Consider fighting her on NG+, when your characters are a higher level and better equipped.
Vicarious Clara isn't necessary here, but it can still be helpful, so if you have access to the skill, don't hesitate to use it.
One strategy I found compelling was to buff your stats to extreme levels, and then attack with Crazy Time, from the Battlemaster class. It's the same one used for fighting Adramelech, the final boss of part 1, and the Armoured Berserker, another super boss.
You want to have a Wind Harpy, a Battlemaster, a Superstar, and a Pope. Anything else is optional, but jobs like the Seadragon Dancer are particularly useful due to her weakness to Time magics. A Wind Harpy can either be Chirp or Pyhar. Either work well, but Pyhar is arguably better for this fight due to her higher evasion. The Battlemaster should be either Luka or Ilias/Alice. Luka is preferable, as he has access to the Valkyrie race. Ilias also does, but she has less health than him. You could always bring two Battlemasters. The Superstar can be either Saki or Sully. Saki starts off with higher stats than Sully, but Sully is better for the late game. Either can work just as well for this fight, however. Finally, the Pope can be anyone. But a character who starts off with the class automatically is the King of San Ilia.
Moving onto the actual strategy. You want to use Sky Dance as soon as possible, which boosts your evasion by 50%. If it runs out, refresh it. While you're not using Sky Dance, you want to use Encouraging Dance, boosting your attack power. Once you have both these up, just attack Nanabi with her other skills, but don't forget to refresh Sky Dance and Encouraging Dance if they go down. The Wind Harpy can use these skills. Next, you want to start buffing your Battlemasters stats in this order: Transform, Inner Focused Mind, Focused Spirt, Armor Break, Crazy Time. While the Battlemaster does this, you want to be using your Superstar to buff the group using Song of Offence, Defence, and Daisy Bell. Once you have both of those up, just use other skills. For the Pope, just use him to keep the party in a healthy state should they take damage, and restore their mana and SP.
Once you finish buffing your stats, you can use Crazy Time, the main damaging skill. It hits six times, and assuming you've increased Luka's stats sufficiently; he should do about 6000+ damage per strike, totalling at 30,000+ damage. Just enough to kill her.
There are better combos than this one, no doubt, but this is the easiest to get a hold of, in terms of grinding.
