Chapter 206: 206

Episode 206: A brother doesn't break a promise to his sister

 

"Hmm, is that so. Yesterday, she went to an E-rank dungeon with her friends who were originally in a party, and before they knew it, only that girl disappeared ..."

 

"Yes."

 

 

 After receiving an explanation from Nanami, I fold my arms and ponder.

 

 

 I think it's a good idea to ask a party member first.

 

 

"So, who are the party members?"

 

"The only girl in this class, is En-chan. I got along with this girl through Alice-chan. I met En-chan at school today, and I only just learned about what happened yesterday ..."

 

 

 Nanami brings a black-haired girl standing nearby and introduces her. I don't know anything about this girl, and she seems depressed because her friend is gone.

 

 

"Nice to meet you ..."

 

"Yeah, oh, yes, nice to meet you. So, what about the Explorers' Union and the police?"

 

 

 I nod to greet her as she lowers her head with a sad face.

 

 

"Yes, I contacted them. It just doesn't look like they're going to move soon ..."

 

"Got it ..."

 

 

 I nod to her, who cut off her words halfway through with an expression that shows her sadness and her disappointment.

 

 

 It's true that the police and the Explorers' Union may not be able to act immediately. Even so, the cause of the dungeon disappearance is still unknown.

 

 

 If the cause is unknown, and they dispatch people without any countermeasures, then if that person also disappears, it will be like a double disaster.

 

 

 I think it's not unreasonable to move cautiously.

 

 

"So, should I go investigate that dungeon?"

 

 

 I think that is what Nanami wants me to do.

 

 

 And, if possible, I'd like to investigate the cause, find her friend, and bring her home.

 

 

"Go ... can you?"

 

 

 Nanami asks me hesitantly.

 

 

 Even though she's always so selfish, she doesn't really want to ask me for things that might put me in danger or cause trouble for me.

 

 When I think that she's worried about me, it's my nature as a brother to want to respond to her feelings all the more.

 

 

"Of course, isn't it obvious? There's no way I'm not going to do something about a girl who gets along well with my precious Imouto."

 

"Thank you!! I really love Onii-chan!!"

 

 

 When I answer with a smile, Nanami once again hugs me and rubs her head against me in front of everyone.

 

 

 I feel very happy at the moment.

 

 

 Yeah, yeah, it's no exaggeration to say that I live for this moment.

 

 

"What? Nanami, did you think I would decline your request?"

 

"Because it's dangerous, and you might even die ... I don't want you to go to such a place ..."

 I pull Nanami away from my body and look Nanami in the eyes.

 

 

"That's ridiculous. There's no way I could refuse Nanami's request for such a reason. Besides, I can't die leaving Nanami behind. I'll come back properly. I promise."

 

 

 After giving a bitter smile, I bend down to meet Nanami's gaze and put out my little finger with a serious expression.

 

 

"But ..."

 

 

 Nanami still hesitates indecisively.

 

 

"I won't break my promise to Nanami, right?"

 

"Yeah, that's right ... That's right. Please, Onii-chan. Help Alice-chan. And come back properly."

 

 

 I couldn't bear to see Nanami like that and ask her again. Nanami closes her eyes and nods while looking back at the past.

 

 

 Then, Nanami also wraps her pinky finger around mine, and we pinky promise.

 

 

"Oh, leave it to me."

 

 

 I accept Nanami's request and nod firmly.

 

 

"So, En-chan ... is that right? I'd like to ask you a question, okay?"

 

"Eh, ah, yes, of course."

 

 

 Surprised by the sudden turn of events, En-chan nods her head in confusion.

 

 

"For the time being, can you tell me in detail about the situation at the time, the place where she disappeared, and what she was doing?"

 

"I understand."

 

 

 After that, I listened to En-chan's story and grasped the situation of the time.

 

 

"Ah, Nanami's house-sitting this time, right?"

 

"Y, yeah, that's right."

 

 

 After listening to the whole story, I warn Nanami just in case.

 

 

 Nanami nods reluctantly as if she really wants to go. If she says she wants to go with me, I will definitely stop her.

 

 

"Yeah. If we go together and Nanami disappears, I won't care about Alice-chan and will do my best to find Nanami."

 

 

 The reason why Nanami is left at home is because of the possibility of this happening. I have to tell her firmly.

 

 

"I, I know. That's why I called you, Onii-chan. I don't know what you would do if I were gone."

 

"Hahahahaa. That's already decided. I immediately take a break from school, thoroughly investigate every nook and cranny of the dungeon where Nanami disappeared, find clues, and no matter where the place is, go there, no matter who the opponent is in the country or the world, I will beat down anyone who gets in my way and search for Nanami until I find her. Isn't that normal?"

 

 

 I ask Nanami, who has a bewildered look on her face, what she thought would happen if my sister disappeared as an older brother.

 

 

""No, it's not normal at all!!""

 

 

 However, the answer ends up being a tsukkomi from the entire class surging towards me.

 

 

"Ehehe, that's right, that's my Onii-chan, isn't it ~ ."

 

 

 Nanami is twisting her body and fidgeting shyly.
