After returning back from Kyoto Tatsuya and the other had once again started their training and Tatsuya had also started to pace up and open his restaurant. He still had some funds left but he didn't want to take any risks.
Tatsuya had also started to increase Miyuki's training once again as he didn't want to see her to be in the same situation which Yasaka and Kunou just encountered. It was true that he would save her as well but what he would do if she could not contact him or he could not reach her during an emergency.
Miyuki was struggling to keep up with his training but after learning about his reason to train her this much from Kurumi, she didn't gave up and tried her best to keep up with him. Tatsuya had also promised her that he would make her a special weapon if she could land a hit on him during the spars.
Tatsuya also went on dates with both Miyuki and Kurumi from time to time as a reward for them to keep up with his training so they didn't complain a bit as they thought that the reward was worth the hard work they did.
Miyuki was also able to land a hit on Tatsuya after a month of training and just like Tatsuya promised he gave her a bluish green sword which looked to be made if ice(basically Eugeo's sword from SAO but slightly greenish colour). The sword was able to manipulate ice and wind without any problem and it could also change its size. The sword's powers also grew along with her.
Seeing Miyuki's progress Tatsuya was very satisfied she had already reached the High high class level and with her new sword she could also take on some of the low Ultimate class beings.
Tatsuya also taught Miyuki how to fly with the help of ki. Though she had troubles in learning ki manipulation but was finally able to get it though her ki attacks are not very powerful so she only uses it for flight.
After months of hardwork he was finally able to open his restaurant. He had decided that he would be the cook and he would ask Kurumi to be her waitress. During the first week of resturant there were not many customers so it was easily manageable for them but after tasting his food more and more people started coming there and the work load on them increased. Kurumi didn't had any problem as she just needed to serve the food and take the orders and had the stamina as a TAILED BEAST to do so but for Tatsuya it was a different story. He was rushed with orders to the point he used shadow clones for helping him cook and buying the ingredients which were depleted at a very fast rate.
Seeing his progress many nearby restaurants tried to cause ruckus in his restaurant but Tatsuya who heard their ulterior motives used his powers changed their memories a bit such that they would just sit and enjoy the food and would leave them a lot of tip.
Tatsuya and the other two also noticed that many supernatural beings would come to dine at his place as well but most of them were either low class or mid class so they were no threat to them.
Tatsuya even invited Kunou and Yasaka to his restaurant and they both were surprised to see the rush in the resturant but once they tasted his food they realised the reason for the rush.
Tatsuya had also started writing novels and drawing manga which were famous in his previous world. He had started publishing Harry Potter for the novel and One piece for the manga. When he went to the publishing company the people there just felt that the child was jus playing around but after reading his work those same people were on their knees in front of him requesting him to publish his work there. Tatsuya who got aware of the situation started leeching out as much as he could. The higher-ups of the company were happy that he decided to publish his work there but still the contract that they made with him was too much for a new writer and they felt that they have been cheated but once his work was published, the hype that it created made those people forget about that and were now happy that they accepted his offer. He kept his identity a secret as he didn't want any more trouble than he was already experiencing and used the pen name 'Saitama'. He used this name because he thought that people at the publishing office calling him 'Saitama sensei' like Genos would be funny.
Right now Tatsuya came out of his house and is now going to his restaurant beside his house. Tatsuya had already employed some of his clones there before he went to his house for some rest and now he was going back to work.
Tatsuya looked towards his restaurant and saw that it was crowded just like always. Suddenly Tatsuya noticed two people outside his restaurant. One was wearing a magical girl outfit and the other was wearing a maid outfit. To a normal person they would look like some cosplayers but on seeing them Tatsuya frowned a bit.
The people were none other than Serfall Leviathan, a devil king, and Grayfia Lucifage, the strongest queen. At first Tatsuya thought that they came to investigate about him and the others but sighed when read their minds with telepathy.
They were not here for investigation. It looked like Serfall and Grayfia met at a comiket that they came to visit. Serfall came by herself to find some material on magical girls and Grayfia came to accompany Rias and after meeting each other they both decided to catch-up with each other. Rias did not joined them and left back for underworld.
Tatsuya thought for a while and then decided to talk with them. He was also interested to meet with both of them as he had seen them in the anime before. He also wanted to take a picture along with Serfall as he had also seen the magical girl anime along with Miyuki who was also a fan and he too thought that it was quite good. He was not flustered anymore as now he knew that they were not here to investigate on him and even if the things were to go south he could easily vaporise them without much difficulty.
He approached them and saw both of them talking to each other while standing in a line to enter his restaurant. He grabbed Serfall's dress with his fingers and lightly tugged it.
When Serfall noticed that someone was tugging her dress she turned around to see who was calling her. When she turned around and saw a cute young boy standing behind her. Grayfia also followed her gaze to see who was calling her.
Tatsuya who saw Serfall's face from a close distance thought that she was very beautiful but still remained calm. He gave her a gentle smile and asked, "Are you doing a magical girl milky cosplay?"
Serfall when heard the boy's question became excited and said, "yes I am the magical girl Levi-tan" and did the pose that she did in anime. Tatsuya thought that she looked cute but still remained calm and said, "I am a fan too, can I have a picture with you?" Serfall heard him and started fiercely nodding her head and said, "yes you can."
Seeing her nod like that Tatsuya started to laugh lightly but seeing him laugh all the girls(including Serfall and Grayfia) that were looking at the interaction between him and Serfall only had one thought, 'CUUUUTE!!!'
Serfall immediately hugged him and started rubbing his cheeks with her's and said, "So cute". Tatsuya didn't mind her as he too felt nice and let her do what wanted. Serfall calmed herself down and looked towards Grayfia who had also calmed herself after seeing his cuteness and said, "Fia-chan will you take our picture?" Seeing Grayfia nod in agreement Tatsuya gave his phone to her and said, "Thank you."
Grayfia nodded and took the picture of both of them and gave the phone back to him. Tatsuya took the phone and said, "Thank you my name is Tatsuya Shiba, Nice to meet you."
Serfall and Grayfia nodded and then Serfall said, "Nice to meet you as well Tatsuya-chan my name is Serfall Leviathan but you can call me Sera-chan or Levi-tan and the one beside me is-" Grayfia bowed and said, "Nice to meet you my name is Grayfia Lucifage." She bowed again and this time Tatsuya also bowed. He then looked at her curiously and asked, "why are you wearing a maid uniform are you also cosplaying."
Hearing this Serfall started to laugh and said, "I told you to wear something else." Grayfia ignored her and said, "no this is my work attire. Tatsuya didn't asked her further about the maid clothes as he thought that she liked that as she even wore it in public places as well. They all started to talk to each other while waiting in the line. Mostly it was Tatsuya and Serfall discussing about the anime. Grayfia was actually not very bothered by that, she even felt a bit gratefull as she didn't had to face the hyperactive girl who came along with her.
When their turn came Serfall looked at Tatsuya and said, "Tatsuya-chan come and eat with us it would be more fun, you don't mind Grayfia do you?" Serfall looked at Grayfia for confirmation to which she gave a nod of approval. She had a good impression of Tatsuya and thought that he was better behaved than a certain red-headed otaku girl.
Seeing Grayfia approving her request Serfall was very happy. She thought that Tatsuya was very cut just like Sona and also didn't acted cold towards her and he also showed interest in magical girls, she was very happy to finally meet someone with whom she could freely talk about her hobby.
She was about to ask Tatsuya again but when she looked back Tatsuya was gone. They both searched for him but couldn't find him. Serfall was very sad but Grayfia comforted her and said that he might have gone back to his friends or parents. Serfall could only sigh and then both of them ordered their food.
While they were talking to each other someone put the dishes they ordered on the table. Both of them were mesmerized by the aroma that came out of the dish but came back from their thoughts when they heard a familiar voice, "I hope you enjoy the food I worked extra hard preparing it for you and I also added a dessert."
They both looked towrds the source of the voice and saw Tatsuya standing there in chef's attire and smiling at them. He bowed to them and then left them. He also used to serve food to the customers while Kurumi was on break and he was also well known among the regulars.
Serfall came out of her shock and said, "Wait Tatsuya-chan you work in this restaurant?" Tatsuya looked back at them and just smiled and then went back to the kitchen.
