17-sai no Teikoku Episode 4

Kiyoshi and Sachi are now aware that Aran's political aspiration was triggered by the death of his childhood friend Yuki, a victim of a scandal seven years earlier involving her father concerning a disguised monetary contribution to Prime Minister Washida. Suspecting that Aran is scheming to take revenge on him, Washida orders Kiyoshi to remove Aran from his post, and this puts Kiyoshi in a dilemma whether to undermine Aran or to defend Utopi-AI. Meanwhile, Sachi reveals to Kiyoshi her discovery that Aran has created a mysterious AI girl character in a hidden room in his residence. (Source: NHK)
