Picking up where season one left off, Juzo Inui (Gun Slave Unit Device 13) has Rosa's data. Although it seems like everyone wants it, either to expose it or to destroy it, really no one is interested in it. Wachowski, the leader of the anti-Extended terrorist organization Spitzbergen, attempts to coerce Tetsurō to use Harmony to command Juzo to destroy Gun Slave Unit Device 7, who works for Berühren. Juzo does eventually fight Seven, but -- between corruption and double-crosses -- Berühren still pulls all the strings. (Source: ANN)

Shuuzou Shuu Matsutani lives his ordinary life in peace. He has friends, a crush, and a passion for kendo. Dejected after losing to his kendo rival, Shuu climbs a smokestack to watch the sunset where he finds Lala-Ru, a quiet, blue-haired girl wearing a strange pendant. Shuu attempts to befriend her, despite her uninterested, bland responses. However, his hopes are crushed when a woman, accompanied by two serpentine machines, appear out of thin air with one goal in mind: capture Lala-Ru. Shuu, bull-headed as he is, tries to save his new friend from her kidnappers and is transported to a desert world, unlike anything he has ever seen before. Yet, despite the circumstances, Shuu only thinks of saving Lala-Ru, until he is thoroughly beaten up by some soldiers. As he soon finds out, Lala-Ru can manipulate water and her pendant is the source from which she is able to bring forth the liquid, a scarce commodity in his new environment. But now, the pendant is lost, and Shuu is the prime suspect. Ima, Soko ni Iru Boku is the haunting story of a dystopian world, and of Shuu, who has to endure torture, hunger, and the horrors of war in order to save the lonely girl he found sitting atop a smokestack.

Yukiya Ayase is a gentle, kind hearted, and innocent university student. The only relative he has left, his cousin Tetsuo, betrays Ayase by selling him to the highest bidder in an auction with hopes of making an enormous profit to be able to pay off his debts. Somuku Kanou, a bad-tempered (though very rich) loan shark, comes to Ayase's rescue and buys Ayase for an impressive 1.2 billion. Kanou apparently knows Ayase from something that happened between them in the past, but Ayase cannot remember who Kanou is nor does he understand why he saved him. In a desperate effort to keep Ayase close to him, Kanou demands the debt be repaid in full and suggests the perfect way to do it: by selling his body to Kanou for 500,000 each time. Ayase is horrified in the beginning, but something soon begins to grow between them that can't be bought for any price. (Source: ANN)
