One-shot of Noble Six's last moments on Planet Reach before arriving in Ylisse. Nothing more, nothing less.

Idoun was a woman who didn't know anything about her past life, and was always trying to find out what it was. Avril was a Spartan IV who just wanted to find something meaningful in her life. Neither of them have anything in common...until something goes awry, and they switch respective worlds. Now, they must find their way back, before a greater evil exploits this for his own gain

When Spartan B312 chose to stay behind, he was suddenly whisked away by an unknown force and sent to the Fire Emblem lands to assist in the war, but will this battle-hardened soldier be able to adjust to their rules of engagement, and more importantly, keep himself from falling into darkness? Not a Yaoi, contains Hetero pairings, confirmed harem for Six
