Chapter 29 - Arrival to Kimetsu no Yaiba.

Ryuu was confused as to why the mission requested for him to not use magic in fighting the lower and upper moon when it was suicidal to even imagine fighting the 6th lower moon for him not even mentioning wounding an upper moon.

Sure he was excited about another world but the task that was given to him is nearly impossible. Ryuu pondered the reason for having the ability when he couldn't even use it.

Though, it quickly died down when he thought carefully to consider that by strengthening his body then he could further efficiently use mana.

This is the reason why mages from the Fairy Tail verse needed to train their body to handle the mana consumption.

Using magic is not directly manipulating the mana rather absorbing and converting it into your magic which is a large burden to the body.

To put it simply, magic is like impure water that has many other elements while the mage's body could absorb this impure water before converting it into much pure water that could be used.

By training the body then you'd improve the efficiency and speed at which it purifies the water. Though, this is putting it in the simplest term possible.

Additionally, this is not like your typical chat mission since oftentimes everyone would be participating.

'It should be a great opportunity to train my body in case I run out of mana in battle.'

Ryuu knew that relying heavily on one thing could leave him vulnerable. He could at least fight by using his breathing technique if he learned to create his own. Though, it was no denying it was a nerf by the system part.

[ Simp For Makima: It seem the first world mission is helping Shinobu kill the Demons (Oni) ]

[ Insect Hashira: Isn't this a perfect opportunity to train your Total Concentration Breathing Technique? ]

[ Simp for Makima: Yeah, but before that, how is everything? I'm curious what part of the story all of you are in? ]

[ Titania: Ah, Lucy recent joined when I arrive back in my guild ]

[ Thousand Master's son: I'm not to sure but I am certain it's close to me fighting Evangeline-san. ]

[ Honored one: I just got the Itadori Kid. These weapons really suit me but I'm not really a weapon user. I prefer using my hand to hand but you never know when you will ever need it. ]

[ Exhibitionist: For me, it's close to the canon story. I am currently training with my peerage. ]

[ Kozuki Oden's successor: Unfortunately, I don't know but Ace is still alive because the Vivre card is still in my hands. ]

[ Self proclaimed Human: I'm currently in Talosheim and recently finished fighting Ice age spear. ]

[ Simp for Makima: Is that so? Don't worry about what you seen, everything isn't set in stone especially now that you know the things that will happen. ]

[ Kozuki Oden's successor: Will I be able to join you? My chains holding me in Wano and leaving it would detonate a bomb. ]

[ Titania: Why do you have a bomb strapped to you? ]

Erza was once a slave that worked on the tower of heaven and felt great pain upon seeing people who experienced the same thing as she did.

[ Kozuki Oden's successor: It's place upon me by my father Kaidou. ]

[ Thousand Master's son: How cruel! How can someone do that to their daughter!? ]

[ Kozuki Oden's Successor: Ah, I'm actually his son. ]

[ Thousand Master's son: What do you mean? Aren't you a girl? ]

[ Simp for Makima: Don't think about it. Yamato is a man. That's it. ]

[ Exhibitionist: Right, I forgot that your dream was to become Kozuki Oden, correct? ]

[ Kozuki Oden's Succesor: Yes! I will be like Kozuki Oden and have my own adventure! ]

[ Self proclaimed Human: Whoever this person sounds like is an admirable person. ]

Those who knew about Oden couldn't help wryly smile. Admirable? Yeah right.

[ Simp for Makima: It's likely the chat group will protect you from harm. When we meet, we would try our best to free you. ]

[ Kozuki Oden's successor: Really? Are you able to do that!? ]

Yamato was excited at the chance to be free and taste the thrill of adventure that Oden experienced long ago.

[ Simp for Makima: Of course, that's what the chat is for. Anyway, I have to go and meet up with Shinobu soon ]

[ Self proclaimed Human: Well, I hope you two have the best of luck. I've watched some of her stories and their abilities seem to be around B to A class adventure in my world. ]

In the world of Lambda where Lambda lived Humans and other races had their power is vaguely classified by the typical adventurer classes. G, F, E, D, C, B, A, and S class adventure.

Those at the B to A are capable of slaughtering thousands upon thousands of elite soldiers alone including mages. They are able to decimate a whole kingdom alone.

If it was compared to Rias world, the Draconic Deus would be around a High-Class Devil while an S Class adventurer would be around a Peak of High-Class Devil.

[ Honored One : They seem rather high grade curse spirit if the upper moon seem like comparable to 1st grade to special grade. ]

In Jujutsu Kaisen, cursed spirits are ranked from 4th to 1st grade curses with special grades having human intelligence.

A 4th grade can be dealt with simple wooden bat but 1st grade tanks might be useless to harm it while a special grade needed a cluster bomb to be harmed.

[ Thousand Master's Son: Good luck @Insect Hashira and @simp for Makima ]

[ Titania: In my world, they would at least be a tricky opponent but not enough to be S Class. Wish you two good luck. ]

[ Exhibitionist: It seem we won't be able to chat for a while. ]

[ Self Proclaimed Human has sent 50x 2nd Grade Healing. ]

[ Self Proclaimed Human: With this you all be safe. It can heal fatal wounds but wouldn't be able to heal lost limbs or eyes. I hope this is enough. ]

[ Simp for Makima: This is extremely useful, thank you, Vandalieu-san. ]

[ Insect Hashira: It would be a great help in saving and fighting the Demons (Oni). Thank you. ]

[ Kozuki Oden's successor: I hope you succeed and I'm able to join. ]

Ryuu felt anxious about winning after receiving several many items from the other members. He wholeheartedly accepted the items and needed to prepare for the mission.

[ Simp For Makima: Alright then thank you, @everyone. Shinobu-san, I'll just go ahead to prepare. ]

[ Insect Hashira: Pardon but would you arrive straight to my Butterfly mansion or would I have to find you? ]

[ Simp For Makima: Hmm that is troublesome. I'll just call you using the Chat group if I somehow arrive in a different place ]

Everyone went offline because the mission was not for them to think about. Ryuu went to check the [ Store ] to buy some kimonos and Yukata to help blend into their world. Furthermore, he always wanted to wear one and it's difficult to find them in his country.

Ryuu chose a dark yukata with a gradient of red at the bottom that had an inner high neck similar to demon slayer uniform but was dark in color rather than brown. He looks at himself in the mirror and smiles at how the clothes perfectly fit him.

Additionally, he added sheets for the dagger around his waist where he was able to take it out rather quickly. Ryuu could always store it in the inventory but prefers it that way.

'Hold on, I can't use magic but it didn't say Items are excluded. Maybe I could still use the [ Mid Tier Holy Dagger. ] in fighting Demon. Maybe I could modify it with the help of a blacksmith.'

He wanted to add chains at each end of the blade similar to Uzui as it was his calling. Ryuu took out the dagger in hand and twirled it around before nodding to himself as he checked his phone.

'Hope I arrive in the butterfly mansion or close to it.'

[ Would you like to start the mission? ]

[ Yes/No ]

Ryuu picked [ Yes ] before his body started to feel dizzy and his vision a bit distorted, having difficulty comprehending the sudden change. Soon he was able to see that he was currently in a forest where the scent of a strange aroma could be smelled.

He took out his phone to see where he was and found that he was below the mountain where the [ Demon Slayer ] corp was located.

[ Simp for Makima: Shinobu-san, I'm at the foot of the mountain. ]

[ Insect Hashira: I'll head there. With my status, they won't try to question your entrances. ]

Ryuu nodded and decided to wait for her since he doesn't want unnecessary conflict with the Demon Slayer corp. He sat down and unsheathed the two daggers at his waist.

He did a few swings and slashes to find the perfect form of Total Concentration Breathing Technique. Ryuu without magic is capable of at least evenly fighting a 6th lower moon where he barely survives.

It was unsure if his Holy blade has the edge when it comes to killing Demons (Oni) as they are malicious creatures.

"Ara~ is that you, Ryuu-san?"

Shinobi soon arrived to see him and was taken aback by his new appearance that made her oddly attracted to him. She had seen his appearance before his transformation and the difference is uncanny.

"Yes, you look beautiful up close."

Ryuu wasn't trying to flirt nor compliment her; rather it was what he genuinely felt as compared to the anime, then she looked unbelievably beautiful. It was like a top-tier cosplayer in front of him.

"I could say the same thing to you. Tell me what happened?" Shinobu was curious and captivated by his new appearance.

"Hahaha thank you. Let's go, I'll tell you along the way."

The two brazenly walk their way into the peak of the mountain trying to enjoy the company of each other. Shinobi wanted to know what kind of person the one that had helped her in saving the people that she cared about.

"My appearance changed due to a reward from the system that cleanse impurities. Like it removes horrible stuff in the body."

Ryuu explained while Shinobu found him rather entertaining. He seems honest and doesn't have a lot of things along with being a bit immature despite having the same age. Though, their life experiences differ.

Sure Ryuu lived in a rough area that can be considered as a slum to some people but compared to Shinobu then his pain is lesser. Still the two shared one thing in common. The loss of close family.

"I know what you're saying. You know, I've studied medicine, remember?" Shinobu giggled a bit seeing his reaction.

"Oh right, sorry. I just don't know much about common sense in this era. My time is at least a hundred years from now." Ryuu answered honestly. The Kimetsu no Yaiba is set around 1912 to 1926 with Ryuu coming from 2024.

"A hundred years huh? I wonder if I could visit your world and study them?" Shinobu is curious about what the future is like.

"Maybe I could bring you with me? After everything."

His words struck Shinobu who pondered about what she would do after ending the torment of the Demons and freeing people from them. Whole her life it was fighting and killing demons with the bleak thought of dying on the battlefield.
