Dungeon System Within DanMachi

As Seo was walking through the stairs going towards the safe zone he was talking with his system about something that bugged him....

Seo : System what does the "Hard Skin -E" do and why is it considered a Superior Ability??

{Hard Skin - E = Enables the user to harden any part of his body and grants him 50% Defence}

{This Ability is evolvable the more you use it after it reached SS it will become Metal Skin and then Adamantite Skin....}

Seo : Ehh and what does it do???

{Hard Skin - 50% / Metal Skin - 75% / Adamantite Skin - 100% defence upon activation.....}

Seo : so I will have double the defence add my regeneration in play... COOL!!!!

{Of Course if Host finds and gains the advance ability you can replace it with it...}

Seo : Hmmm I'll leave that for the future.....

As he was talking and for many other things he finally reached after 3 hours the safe floor.....

He went to the town as he wanted to find anything useful... he looked everywhere and couldn't find anything.... after spending 3-4 hours to rest.....

He heard a few loud voices from the tavern below where he was resting.....

??? : Hahh??? don't you know where the fuck she is now??

??? : Why did you piece of shits sold her away???

??? : But she was useless!!!!

??? : She couldn't do a thing always fainted here and there.....

??? : Hah??? how many times have I told you I will kill you if something happens to her....

Seo : Xmnnn??? where have I heard these two voices.....

He walked down the rooms and reached the hall where the ruckus was happening.... it was a total of 3 people arguing about a girl.... it was then the two of them saw him and started yelling at him....

??? : It's you!!!!

??? : You!!!!

Seo : Hmmnn??

After Seo looked at them... he finally remembered them they were Rick and Walter of the Ishtar former family.....

Seo : Oh..... it's you guys.....

Rick : You motherfucker you tricked us.... your name is not Seion.....

Walter : But Seo....

Seo : And?? what are you trying to say??

??? : Was it you???

Seo : MMmm you are??

Seo looked at a wild lady that has brown skin and wears clothing reminiscent of a dancer. The clothes were so revealing that he thought she wore only her underwear.....

??? : Your doomsday..... return Haruhime!!!

Seo : Hah??? are you drunk?? why should I return my hard-pressed earned Maid???

Black lines appeared on the girl.... when she heard that.... he had a friendly relationship with Haruhime and she was really bold on protecting those she cares about....

Seo racked his brain out in order to find which character this bitch was.... he was a hardcore fan of all animes he just liked to pass his time.....

Therefore there were many things he may have skipped them...

Seo : And again who are you??

??? : Ask My Sword!!!!!

She drew the sword that was behind her and revealed it inside the tavern.... it was a wooden greatsword that has noticeably longer handle and the upward curves the blade a bit.

Seo : No time to deal with you... but as for you two..... try anything funny again and I'll kill you.... you haven't forgotten your oaths now do you...

Seo then proceeded to leave as he was bored to deal with her..... no more importantly he couldn't remember her.....

If she was someone important to Haruhime and killed her... how is he going to get the heart of her maid???
