He possess multiple fraud identity in America alone, all with their own SSN and pay his taxes without fail.

Eventually, his name is used as a reference to an organisation rather than an individual.

Plot (Visual Novel) Edit

Grisaia no Kajitsu Edit

He does not appear in Grisaia no Kajitsu. However, his influence on Yuuji's life can be identified on several occasions.

Grisaia no Meikyuu Edit

Heath Oslo plays a big role in Yuuji's tragic past.

The Cocoon of Caprice Edit

He first introduces himself as Kirihara Rei to Ryouji Kazami during one of their meetings to discuss an artwork that Kazuki made. When Yuuji came home, he took interest in the boy and gave him a piece of chocolate. He often interacts with Yuuji when he was a child whenever he visited the Kazami household.

After the death of Yuuji's parent, Oslo took the boy in as an adoptive parent. He usually dresses the boy in girl costumes and sit him on his lap for his entertainment. However, after he witnessed Yuuji brutally kill a man in his mansion, he began to see Yuuji's potential as a killer. Hence, he enrolled Yuuji in one of his "schools" specifically design to train child terrorists. He regards Yuuji as special, and often visits him for a private lesson in knife combat despite his work.

He was also at Yuuji's "graduation ceremony", where Yuuji was pitted against a girl in a life-or-death combat in which the one who survived gets to graduated. Initially pleased with Yuuji's performance, he becomes irritated after Yuuji hesitate and stop trying completely. After Yuuji recovered from the injury, Oslo assigned the boy on an assassination mission, not wanting to give up hope in Yuuji's potential. He was shown to be pleased when informed of his success, noting that a slighly problematic child is a part of what makes them cute.
