Is It Wrong To Get Love In The Dungeon?

'Uugh.... I will never be used to this feeling' I wake up and feel my head hurt like having a light migraine. 'Est... Est-chan.. are you there' I said to Est telepathically while holding my head.

[I'm here, Onii-chan]

'What is happening, Est? Where am I? This is... a wasteland.' I start to regain my vision and I can see fire camp in front of me.

[Onii-chan is open the reward and being sent here to receive it.]

'What kind of gift that send me here.' There's nothing here except cliff, stone, valley, and sand.

[This place is for training onii-chan. Onii-chan won't feel hunger and thirst while being here. The training onii-chan going through is an inheritance. Since it's too big to be received, Onii-chan gonna learn it directly.]

'What kind of inheritance is it?' I start to get up and stretch my body. I turn my head to look around and surprise looking at 3 people behind me. 2 men and 1 woman. 'Ah... Sh!t'.

[Onii-chan needs to ask them what kind of inheritance that Onii-chan's get.]

'Yes Est, Just for this time I know what I'm getting is it gonna be all three of them or just one of them?' I said while looking at them.

[There's 2 of them that gonna give you the inheritance. Only the red and the black one.]

"So You are the one that gonna get our inheritance. Who are you? are you, me?" Said the black one to me.

I can only smile awkwardly at him while thinking for a story to tell him. Yes, I'm looking at the same exact copy of me. Older, Plain expression. Or it could be said that I'm a copy of him rather than the former.

"No, brother. I'm your twin brother, but how? You're alive...." I said with disbelief face toward him. He looks at me surprised "You're my brother? So I have a brother in a different timeline. I'm Siegfried inside the Throne of Heroes. So can you tell me your timeline's story, brother?"

"Of course brother. We're twin brother, so our parents named me Alan Siegfried while you're named Sigurd Siegfried. When we're small, we like to play a lot and you found this little girl that being bullied and we take care of her and play with her. Her name is Kriemhild, but one day the royal guard comes to our house and announces our family as a traitor by kidnapping the princess. Our parents sacrifice themself to let us run. We run toward the jungle and being chased. We're being cornered at a cliff which at the last second you shield an arrow for me while we fall into the river.

I then woke up inside a room while being nursed by a little girl with her grandpa. Later I was being told that you're already dead and I buried you. I swore on that day, I will get us our revenge. One day while I was training, I blacked out and here I'm. Am I dead brother?" I look at him with a longing expression.

[Name is registered Onii-chan.]

Before I ask what name to Est. I hear Siegfried sigh and look at me "No, brother. You're here to get mine and his inheritance." "If I only get both of your inheritance. Why is she here? Is she your wife or his wife?" while pointing at the woman even though I know who she is.

"Hmph... If I don't need your help I won't tell you my name. My name is Atalanta. Archer of red. I'm here because I need to ask you, to deliver this bow. Your world has God in it. I need to present this bow to Artemis-sama as thanks for her help." She said to me. "What do I get from helping you? You know there's no free meal in this world." I said to her with a stern face.

She's taken back by what I said since she never expects for me to decline. "If you can get both of their inheritance before the time limit of this space collapse I will give you my inheritance too. Even only a little time to learn, I know it will help you a lot." I listen and tap my chin "Fine, it's a deal. Then who are you?" I point at the man that looks pale.

"I'm Karna, Lancer of Red. I will give you my inheritance and teaching you how to use a lance. You can apply it to spear and also staff weapon." He said without many expressions.

Siegfried start explaining to me "Our time to give you inheritance is 27 years. While in your world only 9 years pass. When you back the canon in your world will start, So use your time to train yourself. In here your level won't go up, but you can still increase your attribute without a burden in your body since the law here is different from your world. First, since you can already feel the mana, We will help you open your magic circuit."

Three of them stand behind me while I sit cross-legged. "B.a.r.e the pain, Stay awake. You will feel pain and numbness around your body for the first few months." Siegfried nod at Karna and Atalanta and start pouring mana into my body.

I grit my teeth and bearing the pain for who knows how long. I fainted when everything is over and sleep for a long time.

I wake up after 3 months and quickly ask to get ready by Karna, the first to guide me is Karna. He gives me the same Vasavi Shakti but both that we use are just a replica to train. We train for 7 years without stopping since weirdly I don't feel tired but still getting beat down every now and then but he still maxes out his skill on the spear, lance, and staff in that 7 years.

7 years later train with Siegfried which for some reason harsher than Karna. Siegfried beat me down until my state becomes half-death, but I quickly get up by the effect of the training realm. I finish maximizing the skill for the sword which is Sword, One-handed sword, two-handed sword, Dual-wielding, and greatsword. I can max my skill because I use another 9 years facing trial from Siegfried, because he summons Fafnir for me to kill.

I succeeded in killing Fafnir and drink his blood while keeping some of the blood for Balmung that I leave in Danmachi's world. I also fuse his dragon's core into my magic circuit which I open 100 magic circuits with the help of those 3 and making it 200 by fusing Dragon's core into me.

In the last 4 years, I spent learning from Atalanta but only managed to learn Phoebus Catasthrope and max my bow and longbow mastery. The year passes so quickly and I even acknowledge Siegfried and Karna as my brothers because I don't have brother before. I also miss Aphrodite and the other sometimes.

"Now before you go back, you won't only receive our skill but also our equipment" Karna said to me. "I will give you Kavacha, Kundala, Brahmastra, and Vasavi Shakti. Kavacha will fuse with your Armor of Fafnir while Kundala can be worn every time you want. Brahmastra will fuse with your eye and can be used anytime but beware of your stamina before using it. You can call Vasavi Shakti since it won't appear in your inventory." Karna said while for the first time in the whole year I can see he smiling and walk away.

"From me, I can only give you two things that can help you. The first is my Balmung from my timeline, I know you might find another Balmung in your timeline. Since you master Dual Wielding let me give you another one and also this..." Siegfried lifts his hand to the air and summons a crystal "This is Das Rheingold, I know about the seal on Balmung in your world. While you already obtain Fafnir's blood you need Kriemhild's blood and Brynhildr's blood. Tell both of them I'm sorry even though they won't know about it since it's a different world. At least my message reaches them. Give them this crystal for their favor." Siegfried said while put his hand on my shoulder "Good luck out there, brother."

Atalanta comes to me as the last person "Hmph... I just want to thank you for delivering this bow to Artemis-sama as my thanks to her. Don't think I give you for other reason. Here, this is Tauropolos the bow for Artemis and the other is the pelt of Calydonian Boar. Just like Kavacha, it will fuse with the armor of Fafnir. You just need to think to change between Kavacha and the pelt."

I bow to three of them even though they thrash me, left and right. Our bond is stronger every year and makes us closer. "Goodbye everyone. I swear I will help your version in every world I visit. Thank you for all this time."

[Onii-chan, 1 minute for the portal to appear.]

'I have left for a long time, I hope they're okay.' I close my eyes while I can feel my body falling through the portal.
