After being teleported to an Island

Many have seen the anime and read the manga of Akame ga Kill about how a mysterious individual dressed in a coat appeared being this Syura, the son of the Honest 1st Minister appears in front of Esdeath and Tatsumi and the bastard uses his Teigu [Shambhala] and at He instantly teleports both Esdeath and Tatsumi to an unidentified southeastern island.

On the island they both encounter a dangerous beast almost identical to Dr. Stylish's monster final form and Esdeath using her teigu [Majin Kengen: Demonzu Ekisu] (Demon God Manifestation: Demon Extract), quite quickly dispatches the colossal Beasts Dangerous but still what would happen if everything was a little different from the original story and during the teleportation it happened that Esdeath appeared completely naked on the other side of the Island alone and instead of being Tatsumi the one who was sent with her it was rather another person, or also because due to a side effect of Syura's teigu the teleportation ended up weakening her and leaving her vulnerable to a human level temporarily.
