Opening an orphanage in another world

Denied. My permission to enter the dungeon all alone to search for any treasure chest or anything valuable for Rean's and Muse, as well as Samurai Jacks and Principal Alice wedding is denied. I should get at least Elise or Kara, or Mother Aries to accompany me, but they're all busy, though there is one more person that I could try to persuade with my best friend, Cupid

"Please Mahsuri! Can you please accompany us to the dungeon!" [Cupid]

"Pretty please" [Charlotte]

"No. It's your own fault that you went crazy with shopping spree the other day, why should I be the one responsible cleaning up your mess" [Mahsuri]

""Please..."" [Charlotte, Cupid]

"..." [Mahsuri]

And there she goes, staring blankly at us once more. I guess the only thing to do is to beg Sis Rafiah for my own pocket money. Right. Steel yourself, she might be a bit of stern when it comes to managing the finance of the orphanage, and as such my own salary, but I know for a fact that she's still the sweet elder sister she was

"Sure. But I will go shopping with you. I don't want you to spend all your salary on sweet. AGAIN" [Rafiah]

"Thank you!" [Charlotte]

Yes! I should just asked her from the start! Now there is no need for me to dive into the dungeon just to search for their wedding gift. Now, just to survey what gift should I buy

"Sure. I am rather free right now. My shift at the merchant guild should start pretty late in the afternoon after all" [Cupid]

"Great! Let us start right away!" [Charlotte]

"Can we go as well?" [Blond hair girl]

"Pretty please" [Cat beastman]

"Let's go go go!" [Charlotte]

And now, Cupid and I alongside a couple of my younger siblings went around, seeing what should we buy. They keep telling us to buy matching clothes for Rean and Muse. Rean with his usual red and black cloth, and Muse with her usual yellow and green cloth is nice, but maybe we should buy them a pair of clothes that's different from what they will usually wear. Wait, to begin with, can we buy clothes as a wedding gift

"How about some nice tea pot. They will move out after wedding, so they are bound to use it" [Cupid]

"I see. Then things like water heater, wardrobe and daily necessities will be a nice one" [Charlotte]

That's a good idea. She is an apprentice at the merchant guild after all, so I can trust her decision in this kind of thing. Thus, all of us went around and around, until we are too tired to walk. Before we know it, we ended up in front of the adventure guild. Maybe we can take a rest here

"Cupid. Charlotte, and you guys as well, what are you doing here?" [Lisa]

Lisa, Cupid's adoptive sister greet us. She replaces Principal Alice six years back as a receptionist of the adventures guild, and true enough, her popularity sky rocketed ever since. As we keep chatting, familiar adventures faces from long back started to swarm us, and started to treat me like a child! They're rude! I am no mere child!

"Where's the cute Charlotte we once adored?" [Female elf adventure]

"True. She's been imitating Ash, but when you gave her sweet, boom, cute Charlotte once again" [Swordman adventure]

"In any case, thank you for what you have done at the dungeon before" [Syah]

"True, the dungeon is now safer because of you" [Mimi]

"To think we are the one used to protecting you, and now..." [Borg]

"I'm just glad they're safe after all these years! They have grown to become strong!" [Lin]

And with all this commotion, she bound to appear

"Guild master Aries!" [Ram's daughter]

"As expected. Whenever the orphans come, you will make a ruckus, albeit a good one" [Aries]

While Guild Master Ram and Gizzere have retired, the one replacing adventure guild master is Mother Aries, and as for Merchant guild, it was their son who takes the position.

Mother Aries is now an S rank adventure, but true to her nature, she rather work on administration side of things rather than going out and do the field work. I guess that's just who she is

"I wonder, when will the next devil invasion take place?" [Axeman adventure]

"Idiot! Don't jinx it!" [Dwarf adventure]

And jinxing it he does, as just outside the adventure guild, a portal gate open, and a strange mermaid cames out of it. The appearance of the mermaids, something off.

"Cupid! Take care of my siblings please!" [Charlotte]

"Alright! You be careful out there" [Cupid]

And thus, I quickly jump into action with Mother Aries on my side. Even then, she didn't forget about commanding her fellow adventures on what to do, and the good thing is that this has become so common that all of us react just by using muscle memory. Action first, think a bit later. Tell that to Mother Aries, and she will knock my head, so better not tell her

As the strange mermaids shoot water magic at random, some of them begin commanding sea creature of various sizes. Some floating whales, so barracudas, and some piranhas. They just strangely floating around the air, as if they have developed a lung to start roaming outside their usual habitats.

"Water Javelins" [Charlotte]

Shooting high speed water Javelins from my pistol with one hand and summoning my water golem with another, we quickly gain the upper hand in this battle. After all, this has become a common occurrence that we are now used to it, but

"That is..." [Aries]

"Water Behemoth!" [Charlotte]

And a strong one for that. It's far stronger, and far more menacing than your usual water behemoth. It is somewhat take an appearance of a hybrid between your typical behemoth and add in shark like features, like fins and gill, even the eyes of predatory shark as well. I wonder, is this how Brother Ash feels like back then, when he first found us
