Eargasm. After falling for this ReAct by MikuxRinxLen, I was led to this:
【デュラララ】ACUTE／平和島静雄・折原臨也・岸谷新羅【合唱】
Mp3 available here! The cover of its previous part Acute by MikuxLukaxKaito. Eargasm. Nothing can describe how awesome it feels to be listening to Izaya, Shizuo and Shinra's smexy voices.
And here are the original and its sequel.
『ミク×ルカ×カイト』ACUTE『オリジナル曲PV』
Mp3 available here! The story is based loosely on School Days without any nice boats. Miku and Luka are both in love with Kaito, when Miku learns that Kaito prefers Luka to her, she goes yandere and stabs Kaito and commits suicide (In ReAct, Kaito is on a wheel chair, indicating that he was injured).
『ミク×リン×レン』 ReAct 『オリジナル曲PV』
Mp3 available here! The sequel of Acute. Miku appears to survived her suicide and now falls in love with Len instead. *So fast? Wasn't she insanely in love with Kaito before??* Rin gets jealous and...I'm not sure what happened, but it looks like Miku's dead. Rin was holding the knife, but Miku told her that 'repeating it is useless', so...it's up to us to decide how Miku died.
