My Isekai Life (mha x mil)

Summoning

Guild Master: Is he?

Priest: I think so.

After they both accepted my abnormality both of them callmed down and started spawning weird things. I couldn't quite follow them. They seemed to be in their own little word. How should I even be possible to follow that gibberish at all.

Guild Master: That must be it.

Priest: 30 years.

Guild Master: That means.

Priest: Yes.

Guild Master: That is quite concerning.

Me: Excuse me! I am still standing here!

Guild Master: We know.

Priest: Don't worry, we haven't forgotten about that fact.

Me: Then can someone please explain to me what is going on?

Priest: 30 years ago we made a summoning.

Me: Okay....

Priest: We all gave up something precious to us and for the priest it is our blood. We made a blood offering to call upon out saviour.

Me: Okay....

Guild Master: You see at that time we faced desperate times and we all knew that we need a hero as a saviour.

Me: ....okay....

Priest: I think you don't get it.

Me: .... I think I do but what has this to do with me?

I saw the guild master face plams himself and the high priest started laughing at me softly. Well I did get that they made a summoning and everything but still what had this to do with me and what made them be this desperate.

Priest: Hahaha Izuku, you are the one we summoned. The hero from another world.

Me: HUH!

Priest: I did expect that reaction but seeing as how skilled you are there is no doubt that you are the hero we summoned.

Me: Wait! But that was like 30 years ago! How am I the one you summoned!

Priest: We knew that it will take time till the one we called will arived.

Me: But there isn't any dangerous now, is it?

Guild Master: On the countrary. The cursed stones you found are the proof that our enemies are back.

Me: Which means?

Guild Master: You see.... the guild of the blue moon slavation is a guild that devots themself to killing all humanity to have the earth cleanes from its deseas. 30 years ago we managed to find their hidingspot and cleanes it. However seeing as these cursed stones pop up, they must have something to do with this.

Me: Oh....

Priest: We already knew that they tried to summon something but we never found out what it was. 

Me: How come?

Priest: Each time we got out hands on some paper it started to self destroy itself.

Guild Master: Protection magic was put on it and we didn't think about it.

Me: I see.... but what am I supposed to do?

Priest: We have hoped to summon an ally that could help us survive each catastroph they throw against us.

Me: *Sigh* So I am up against a guild and whatever they throw at me?

Guild Master: Of course you are not allone.

Me: But why not? Why come out of hiding now?

Priest: If what we speculated was true then they made a summoning using their lives 30 years ago.

Me: so basically whatever is about to happen will happen soon?

Priest: Unfortunately.

Grand Master: It seems so.

Me: And do you even have an idea of what they could have summoned?

Priest: No. With the amount of souls they got.... anything.

Me: Okay but why this town or city?

Grand Master: Because this city exist as long as we alll know. It was the very first city.

Me: And?

Grand Master: It is said that below us there is a dragon vein.

Me: And?

Priest: It is the souce of all mana. With it someone could destroy the world within just a blink of their eyes.

Me: OHHHH!!!! That's bad.

Priest: It is.

Grand Master: But with your power, we will be able to stop something like this.

Okay now they definitelly are delusional!

How in the world do they think I should be able to do that?

I might have wanted to be a hero but this is just a suicidal mission!

There is nothing that tells me that my mana and their whatever thing their summoned is not stronger than me!

Back home I could at least watch my oponent and have a team on my side but they basically told me that it is a one-man-mission with back up but rather no.

The hell?!

Someone get me back to my world please!

I never signed up for this!
