Always Be the Strongest

"Yo, let's go out."

"Huh?"

One day.

Fluga-sama suddenly asked me out and I involuntarily stared at her, mouth agape.

"What the hell's with that face?" Fluga-sama said with a grin, perhaps finding my reaction funny. "Nothing's wrong with a wife asking her husband out, right?"

"Well, of course, but it was so sudden I was kind of taken aback…"

"Haha, my bad. So, you in? You've got nothing to do now, right?"

"Yes, I am."

"Then what are we waiting for? But no inviting the others. Got it?"

"Okay." I nodded and said, "So, what do we do? Go on a trip? Or eat out?"

"Well, those aren't bad ideas, but it's rare that we got to be alone. Isn't there something more fun to do?"

"Something more fun to do…"

Something the two of us could do other than going on a trip or having a meal outside—or in other words, other than going on a date…

"E-err, you mean child-making…?"

"Y-you idiot?! That's not what I mean?!" After screaming with a bright red face, Fluga-sama shyly averted her eyes, saying, "W-well, not that I mind it…"

Her embarrassed figure is so cute, as I thought so, Fluga-sama cleared her throat and said, "So, what I was trying to say was, let's spar. You know, for training."

"Training…"

But why should we…? I was dumbfounded then Fluga-sama put her hands on her waist and said, "There's no denying that you're strong. You are strongest man in the world, both in name and reality. However, that's only limited to 'this world'. In outer worlds, there may be people who're stronger than you."

"Outer worlds…"

That reminded me, the goddesses had explained it previously. That 'World of Oblivion' was a place where 'filth' from groups of different worlds ended up in.

And that there were countless other worlds similar to ours.

"Do you mean to say that someone from the outer worlds may invade ours?"

"Yeah, we can't rule out that possibility. Remember the 'superpowers' created by that oni? It worked in a different way from skills, right? There must be various kinds of powers in outer worlds, just like it. One of them may allow the user to cross worlds."

"To cross worlds…"

"Right. If that's it, then it's fine. But what if there's someone who can seal or nullify our skills? If there is, they may nullify your immortality and kill you."

"That would be… troublesome…"

If such a person really existed, I would be helplessly killed.

This was certainly a problem that should be feared.

"That's not even the worst of it. There may even be power to stop time, rewind time, steal others' powers, and wipe out the whole world in an instant; hell, someone may even not have the concept of 'death', making them unkillable. Those powers that can rewrite common sense of the world may exist out there. Well, it's just a possibility, and whether they do exist or not, I've got no clue." Fluga-sama shrugged her shoulders, but Elysium did steal Phinis-sama's power.

It was highly likely that they existed.

However…

"If I were to face up against an opponent with such powers, I think I'd be helpless to do anything…"

I mean, I got no power to prevent the world from being wiped out instantly…

But.

"Isn't that the point of 'training'?"

"No, training…?"

Will I really be able to reach a level where I can resist such absurd powers by training?As I was being skeptical, Fluga-sama said with a fearless smile, "To be frank, your growth rate is abnormal. Moreover, your skill always evolved in ridiculous ways. Just think about it, your"Substitute"evolved to "Immortality"so you can absorb all wounds of the people you want to protect. I believe your will made that possible. So, getting the power to nullify 'skill nullification' should be a piece of cake for you."

"Eh…"

"Don't 'Eh…' me. I don't wanna see my man lose. So, make sure you never lose. If time is stopped, move within it. If your power is stolen, steal it back. Show the people who dared to invade our world that you are the strongest man in all worlds."

"Fluga-sama…"

Fluga-sama said so with a straight face, and I replied with a strong nod. "—I've got it. Nothing better than being prepared to deal with any situation, anyway. I'll do what I can."

"Oh, now that's my man. You can never lose." Fluga-sama smiled widely, and I nodded again, "Yes. I promise."
