The unbreakable duo

What do you think would happen if Levi ackerman met Sebastian michaelis well if you want to find that out then you will have to read this story where Levi and Eren both get eaten by this weird Titan [ note that this is before eren turns into a Titan shifter ] not an Abnormal but a new species of Titan that no one knows about until now and go through this weird portal in the Titans schomach and get trapped in the Black Butler era and land smack dab in front of the Phantomhive manor

I do not own anything but the story
