Free The Devil Is a Part-Timer!, Vol. 1 by Satoshi Wagahara

Peaceful! You can make the area around Hatagaya station happy for everyone. And I wouldn’t have to fight anyone I don’t have to. Would you consider it, at least? You, and Alciel, living here until you’re dead and buried?”
    “Alciel is a valued assistant of mine, I’ll grant you that. But why would I want to live all the way to old age with him?”
    “Well, you know, I heard that sort of thing is getting popular these days.”
    Maou scrunched up his face at the concept.
    “Look, Emi, are you…
suggesting
something, when you’re ordering me to live with another man my whole life?”
    “No! Of course not! I just wanted to…bring up the idea, all right?”
    Emi took a breath. “I just want you to give up Ente Isla for me. I want you to give it up, and find a new life for yourself here. On Earth.”
    Maou was quick to respond.
    “Not happening. I’m gonna make my way back to Ente Isla…and it
will
be mine.”
    He meant every word of it. He had lost a great many things, but the strength behind his avowal still rang true.
    That much was clear to Emi as well.
    “…All right.”
    “Is that all?”
    “Yes. That’s it. Now it’s been decided. I will chase you down for all time, until you are dead by my hand.”
    “So the same as before. Great.”
    Maou placed his feet upon Dullahan’s trusty pedals. He pumped them once, defiantly, hoping to place a final exclamation point on their conversation, when:
    “Yagh!”
    He felt a dull force thunk against his front wheel. Losing his balance, he fell lamely to the ground.
    Even Emi, who was about to briskly walk away from the scene, was surprised at the sheer artistic grandeur behind the wipeout. If he were a little closer to the side of the street, he might have cracked his head open on the curb.
    The cup of iced coffee in his hand arced through the air, the liquid and ice splattering across the pavement.
    “What was
that
?”
    Without thinking, Emi ran back to Maou, helping him back up.
    “Oww… Man, that came out of nowhere. Did I run over something?”
    “Hah! And you call yourself Devil King! Get it together, won’t you?”
    “Shut up.”
    Emi inspected the bike as he supported Maou’s side. His eyes had teared up a bit from the shocked surprise.
    “That’s a new bike, too, isn’t it? Oooh, too bad.” She pointed at the front wheel as he brought the kickstand down.
    “Aw, man, it’s flat!”
    Falling to one knee, Maou groaned in pain as he realized the enormity of it all.
    For a moment, Emi reveled in the sight.
    “Come on, Dullahan! You can pull through this! It’s just a flesh wound! I’ve only just purchased you!”
    But seeing Maou whine emphatically at a cheap fixie made her feel a twinge of empathy instead.
    “You don’t have to act like that. It’s just a flat. Just bring it to thebicycle shop tomorrow. It’s only a thousand yen or so to patch up the tube. Replacing a tire costs more, but…”
    “R-really?!”
    Maou’s hands still tightly embraced Dullahan as his head turned toward Emi, who edged backward in response.
    “Um… Yeah. Really. But get away from me! You’re all dirty! It’s disgusting!”
    “I am
not
disgusting! But…okay. I’ll go get it fixed first thing in the morning. Thanks for the help.”
    “You’re welcome… No! Wait! I don’t need your petty compliments! You were just acting so pathetic over a stupid bicycle flat, it threw me off guard, so…”
    Emi failed to finish the sentence.
    “Huh? Earthquake?”
    The ground palpably shook underneath them for a moment. Before she could check up on Maou, they heard a faint bursting sound emanate from somewhere. This time, the rear wheel had blown.
    “Whoa!”
    “Agh!”
    Just when they had a spare moment to shout, the signal light above them shattered into a million pieces. The Hero and the Devil King covered their heads at the sound of shards scattering across the ground.
    “Are we…”
    “…being shot at?”
    They were answered by a cracking sound at
