V.S.S.E. International Affairs Agent (as Abacus)
Marisa Soleil (マリッサ･ソレイル, Marissa Soreiru) codenamed "Abacus" is a double crossing agent who had told V.S.S.E. about who is the person that really killed the President of Caruba, Xavier Serrano and helps out Richard Miller clear out his name.
Posing as Abacus, Soleil claims to know the identity of Serano's killer that will help Miller clear his name. Abacus is also one of the few V.S.S.E. female agents but to protect Soleil's standing as a V.S.S.E. agent, the agency christened her as Abacus. Soleil is a graduate from a university located at the United States of America. After being involved with the R&D of a corporation dealing with the black market, Soleil resolved to live more responsibly ever since. Soleil is being held captive within the Kantaris limits from the organization's suspictions that Soleil is attempting to leak information to Miller.
~ Marisa Soleil, when Kantaris began interrogating her
Richard? My name is Marisa Soleil. I'm the one who sent to V.S.S.E. as Abacus. A mercenary in Caruba named Ricardo Blanco is the real assassin of president Serrano. You should go there and find him. He's your man. But right now we have to get out of the ship. She's going to blow!
~ Marisa Soleil, giving Richard Miller the information on who actually killed president Xavier Serrano
[Serrano: Senorita Soleil, where's Senor Miller? He supposed to be here hour ago for the award ceremony.] Mr. President, Richard mentioned that he had to take care of some urgent business. I thought he'd come, but I guess he changed his mind.
~ Marisa Soleil, informing Xavier Serrano that Richard Miller would always be busy
