Washington D.C | City Park
Reaching the other side of the river, Midna looked at the sky "Airborne monster.. we need to find cover" She spoke already moving towards the closest thing that could be used as a roof "Whatever is coming most be big for the strength of its screech". The twili remembered dealing with flying enemies in her adventures, so she had her javelin at hand again while also forming the net that she used against the demon monster that Julius and her fought at the complex building.
Washington D.C | Palutena's Palace in the Sky
Not hesitating for any moment, Toriel rushed through the door and found herself back in her apartment, she quickly went to her room and locked the door again. Even though that she and Sans shared the apartment, thegoat monster still needed her privacy, more for the things that she hid from the skeleton, things from her life as a queen. Going firectly to her closet, the furred female opened it and then pulled a rather big chest, opening the lock with a swirl of her fingers, it opened and showed its contents, but the object on top was her crown.
"Oh Asgore.. it still shines despite so many years" Toriel spoke to herself as the memories of her former life passed through her eyes, which then focused on the pieces of equipment below the crown. There were dents and scratches in the armor, it looked clean, but she still remembered the blood that coated it. That war was an absurd thing that killed so many innocent.. but she as a Queen had a duty to fight for her people, and this was a similar case as a powerful enemy was being summoned.
It took her some minutes, but Toriel managed to put her suit of armor, surprisingly, it still was comfortable for her body, a bit fit since she grew and the lack of actual fighting in decades. Her eyes then searched for the next object she was looking for, behind her robes and withing a glass frame stood her trident. Asgore, while a kind man with the heart of gold, was also a marvelous fighter, and his wife wanted to follow him in battle, it took some convincing at first, but sooner or later, both monsters started training with magic and physical combat.
Taking the trident and prepared to leave, the queen couldn´t help but see herself on the mirror, ready to fight once again.
