gun soldier in another world

It is in the night where monster attacks begin. John and Erika go out in their room because of the noise then he asks Erika about the noise and when she says it's a monster attack

John was surprised that he created a rifle, the guild master also goes out in her room and says

Guild master: prepare for battle erika

Erika:yes sister!!

John was surprised by what he heard

John: the guild master is your sister?!

Erika:no time to talk let's go!

John and Erika hurriedly go out in the building and the first thing they saw outside is a monster called Ogre

John shoots as quickly as possible the head of the ogre and they save the children that were nearby

John:go inside the building it's safe

The children ask john where are their parents

John:I promise you i will find your parents

The children hurriedly go inside the building where the guild master is in

while she called for reinforcement to hunt other monster

As the guild master goes out in the building she sees a terrifying monster twice the height of a man so she kills it using her ice magic with full killing intent in her eyes

right in the neck of the monster as the head separates in the body of the monster

As the reinforcement magician and swordsman have come the guild master tells her order

Guild master:half of you all is with me while the other save the people now let's go!

Yes maam!

The guild master goes into where John and Erika is

Guild master:glad you two are fine
