Homicidal Oka?

In Deadication, Ayano spared Osana, befriended Amai, Kizana hurt herself on accident, Oka went to Russia with Zaytsev (they went as friends), Asu was arrested for coke problems, Muja was sacked, Mida was found dead in her apartment, Osoro was suspended -again-. Hanako was befriended. Megami went to Italy for a while. No word on when she'll be back.

After watching numerous students die, Oka has developed moderate post-traumatic stress disorder (PTSD). This, along with her crush on the Russian, has driven an innocent cinnamon roll to commit murder and make Zaytsev hers forever. Oka wasn't a Yandere by choice. She was forced into it because of her PTSD. The most frequent nightmare she has is one in which Zaytsev goes to war and dies. As he is a Russian, he cannot bear the thought of fighting against his native Russia.

Zaytsev is the Senpai, not Taro. He's already with Ayano and is my character's good friend. Ayano succeeded and poor Kamarov has no clue about her true nature. Ryoba has succeeded in killing the Journalist. Before Info-chan can die, she has another client... Oka Ruto.
