A Dangerous Beauty: A New Final Fantasy Record Keeper Event
About the event
Serah discovers she must rescue her disappeared sister, Lightning, from Valhalla, and save the timeline. Meanwhile, Lightning is the champion of a goddess in Valhalla, and has only one memory, that of Serah.
The event allows you to unlock Serah, Fang, Sazh, and Snow, as well as a wardrobe record of Lightning's, giving her the Knight of Etro outfit from FFXIII-2. You can unlock the first Memory Crystals (to break the 50 level cap) of all 5 characters, and the 2nd Memory Crystals as well of all the above but Lightning (to break the 65 level cap on some characters). There is also one Soul of a Hero (allowing you to unlock a character you don't currently have), a Memory Crystal I (to break the level cap of 50 for any character), and a MCII (to break the level cap of 65 for most characters)
You can also unlock the accessories Serah's Pendant (500 HP, +15 Resistance) and the General's Belt (+10 to Attack, +15 to Defense).
More details below
The Event movie (Not the best video, he shows the whole event opening as well as the Event movie)
Serah can use daggers, swords, bows, rods, and staves as weapons.
Armor choices include hats, robes, and bracers.
As a caster, she has access to white (3 stars) and black (5 stars) magic.
At level 1, she has 170 HP, 7 Attack, 6 Defense, 12 Magic, 9 Resistance, 9 Mind, 20 Accuracy, 20 Evasion, and 92 Speed.
She is Lightning's younger sister, and spends the entirety of Final Fantasy XIII in a crystallized form as a l'Cie who completed her focus, which was to tell the heroes to save Cocoon. At the start of XIII-2, she is revived with a fleeting memory of Lightning, as well as a need to find and save her.
As for her role, she fills the same role in the group as Vanille in FFXIII.
