Malice@Doll is a 2001 Japanese computer generated original video animation directed by Keitarou Motonaga and written by Chiaki Konaka.
Upon discovering her damage, Joe Admin sends Malice to the repairer residing in an upper area, warning her that Devo Leukocyte, a former bodyguard unit, had forgotten his original programming and became hostile to anything it crosses.
After narrowly escaping Leukocyte (with the help of Meliza), Malice happens upon an area she never saw before and is guided by a little spectral girl holding a ball to a room containing a large, stone-like structure/machine.
Upon speaking to the machine, a tentacle-like monster bursts out of it and brutally assaults Malice, causing her to black out as the spectral girl watches.
Heartbroken, Malice kisses Meliza, causing the latter to revive and mutate into a monster that defeats Leukocyte (at the cost of her own life).
An encounter with the repairer unit she originally sought out upsets Malice even further, causing her to return to the red-light district to seek comfort with her fellow Dolls.
The only one to resist the temptation is Joe Admin, who shows Malice the result of her actions, namely, the pain and perverted madness within the hosts of the infection.
