When cheerful and happy meets depressed and suicidal

(A bunch of roleplays that have been kinda compiled, this is an UTAU story) Aces and Kiki have been plotting the perfect plan of getting their UTAUs together. Kokoa has had her heart broken by her crush, Kaeru Kowairo, pretty much because he didn't really seem to know that she existed. Hachi is always depressed and self-loathes himself and tries to commit suicide whenever he gets the chance. Kiki can't stand hearing Kokoa sobbing all the time because it gets on her nerves and would rather that Kokoa would just be her normal bubbly self again. Aces is sick and tired of having to grab Hachi away from the noose and smacking the daylights out of his face to bring him back to reality. Aces is just sick and tired of having to her suicidal UTAU's weapons and thinks he needs to be changed big time!
Kiki and Aces come together and decided it best that these two should be shipped together for the sake of everyone and for the two utaus themselves. What's going to happen next as you delve deeper into their lives? Just start reading and you'll soon find out.
