Ruri (Seiran) is a 4 stars Assault character in Artery Gear.
Ruri is the upgraded/stronger version of Grace, although I think Grace is still the better fodder farmer due to the ease of skill maxing and much easier to gear.
Ruri specializes in cleaving for PvP, where she can literally clean the entire enemy with S3 -> S2 combo, especially when paired with Alice. Without Alice, she is still decent, although not as broken. Just this simple combo alone will take you to higher rank PvP until people start using bruiser teams with Della and healers to stop the cleave.
Ruri can also do well in farming fodder, although her S3 -> S2 combo must kill the first 2 waves. Sometimes, at the final wave, she will still have her S2 and S3 on cooldown . Aside from this, she is also quite good in Harpist and Octopus, helping you kill the puppets in lower difficulties so you have an easier time dealing the the boss.
Overall, she is just a very good unit to have. If you already built Grace, she is not entirely necessary but a very nice addition to your team. However, if you want to climb PvP ranks, she is very much the preferred choice over Grace.
