After the meeting with Azazel Tatsuya and the others have started to train once again as now their presence is known in the supernatural world.
Tatsuya has now made their regim even more intense making them more tired than usual but the girls didn't complain. Miyuki and Irina were now used to it and Ingvild didn't complain as she knew that right now she was the weakest link of the team. She was more determined than the others and the fact that she was a decendent of the original maou made her progress at a rapid pace. She is now at High high class level much to the surprise of the others.
She now actively take part in spars against Miyuki and Kurumi and even fighting toe to toe with them. Her control over her whip has grown to the point that she is able to handle any enemy under a 100 metre radius. She also uses it as a rod or spear as advised and demonstrated by Tatsuya.
Her magic control has grown as well. now she is able to manipulate countless snakes made of water and also able to form a barrier of water for protection. Tatsuya has also started teaching her a but of lightening magic so as to complement her water magic and whip.
Ki manipulation and chakra control was also something Tatsuya started to teach her inorder to make her body stronger and teach her how to fly without her wings. She also learned to strengthen her body using both ki and chakra. She can also use ki blasts but they were no where as strong as Tatsuya's at most her's can crush a giant boulder.
During all this time Ingvild bas also started to show her affection towards Tatsuya but is not as bold as the other members of the Shiba house.
Tatsuya who has indeed noticed this things does not try to remain aloof like most anime protagonists and actively recieve and show affection to her and others.
Not many changes were there among the others. The only major change would be that both Miyuki and Himari were finally able to break through and were now low Ultimate level. Their progress relieved them and Tatsuya a lot as they starting to lose confidence because of their stagnant growth.
Another noticeable thing was that Miyuki had greatly controlled her possessiveness to the point that she usually don't lash out on other team members and some other people who try to approach Tatsuya. She is still vigilant though as she still protect him from random girls on the streets and other people who tru to take advantage of him. She has accepted the fact that Tatsuya could not be bound to her alone but still only the girls she approve could stay near him.
Tatsuya and his team also have occasional meetings with the devils and Vali's teammates as well. At one point Ophis started to visit Tatsuya regularly. She would sit on his lap and made him feed her chocolates and other sweets making the others jealous but they didn't did anything because they knew the power possessed by the loli can destroy the world.
Tatsuya also occasionally goes to the underworld along with his team. He usually go there to check on Misla's condition and whenever he was bored. He has also met Venelana Gremory and the other two maous who came to visit Misla after her health has improved and let's just say that they have a 'good' impression of him.
Sirzechs has also tried a lot to make Tatsuya and Rias meet so that he can intervene her marriage with Riser but everytime he tries to set them up Tatsuya turn his offer down.
In a desperate attempt Serzechs even asked him, "Tatsuya why don't you meet my younger sister." To which Tatsuya said, "I have heard about her from Sona and from what all i have heard from her, she seem to be a real piece of work and very annoying."
Hearing the blunt but true evaluation of Tatsuya Sirzechs's face twitched but he controlled himself and said, "She is nothing like that she is a very sweet girl so why don't you meet her at least once and whose words do you believe her brother's or her friend's."
Tatsuya didn't take even a second to answer and said, "friend's" Sirzechs's face twitched again and asked, "and why?"
Tatsuya place his hands on his shoulders and said, "As a fellow sis-con I know that you can never say I'll about your sister to anyone else." His tone then got colder and said, "And why are you so desperate in making us meet, are you scheming something."
Hearing this Sirzechs immediately shook his head rapidly and said, "No I am not." Tatsuya then smiled and said, "Good then, if you were scheming something which make my family involved in it then from tomorrow there would be one less maou." Sirzechs paled on hearing this and thought, 'It's not worth asking his help, let's just wait for the future and see."
Sona and Serafall has also asked him to join their peerages but were declined but still Serafall tried it from time to time.
Tatsuya also trains with the devils from time to time but not as intensely like he practices with his own team. Seeing their practice his team only thoughts were, "who the hell is this person, where is that hardcore training freak gone. He must be an imposter.'
And just like that half a year passed and right now Tatsuya and his team were getting ready go to the underworld in Sairaorg's birthday. Though they were still humans, Sairaorg said that he has only called some people who were his or his mom's friends.
Once everyone was ready Tatsuya created a magic circle and teleported with everyone else. Once they reached the underworld Tatsuya knocked on the door of the mansion and after waiting for a while a maid came to open the door.
Once she opened the door and saw Tatsuya and the other she smiled and gave a bow to them and said, "Follow me, I will lead you to the hall."
Tatsuya and the others nodded and silently followed her. While on the way Tatsuya thought, "Everytime I think of something to not happen, it always happens, lets try to think opposite of that. Today I will meet the 'switch princess.''
While he was thinking that they reached the hall and made took her leave. Tatsuya who was still thinking was brought out of his daze when he was sandwiched between two people and he thought, 'soft' and then looked at them and saw both Misla and Venelana there.
He then moved back and said, "Sorry about that, good evening Misla-san, Venelana-san." Both of them did there 'ufuufuu' chuckle and said, "Good evening to you too Tatsuya, Miyuki, Himari, Kurumi and Ingvild."
Misla then came forward and said, "Thank you for taking some of the time from your schedule and visiting us."
Hearing her Tatsuya gave a wry smile and said, "You are still upset for not coming here more frequently Misla-san." She just smiled and said, "There is nothing like that and besides, for Tatsuya-kun his work is more important than us."
Tatsuya gave a tired singh and said, "I will try. to find time to come here more often."
Soon Sairaorg and came with his peerage along with Sona and Tsubaki. Seeing them Tatsuya and the others moved towards them and said, "Happy Birthday Sairaorg." Sairaorg who saw them became happy and immediately put his hand around Tatsuya's neck and said, "Thanks you guys, say Tatsuya today you will not reject my request of sparring with you right?"
Hearing him all the people present there gave a ired sigh and said, "He never changes." Tatsuya looked at him and said, "Okay I will fight you once the party is over and her you gift." Sairaorg's smiled and took the gift and said, "Shall I open it now?" Tatsuya shrugged his shoulders and said, "Your wish."
Sairaorg hurriedly opened the gift and seeing his antics all of them smiled and it was to be expected as it was the first birthday that he was celebrating with his friends and family as before his mother woke up he didn't organized such events.
Once the box was opened there were different bands present in the box. All of them looked at the band's intently and Tatsuya said, "Those are some training band which can help you in training. You can change their gravity according to your will without affecting your whole body weight. You can change the gravity upto 10 times the gravity of Earth. I use similar bands as well(though mine can increase the gravity upto 500 times that of Earth).
Sairaorg's eyes were now shining on seeing the band and he bear hugged Tatsuya and said, "This is the best gift ever."
Tatsuya who was being crushed by the hig sighed but smiled later and said, "I am glad that you liked it." Tatsuya then heard Sona and Venelana talking.
Sona looked at Venelana and asked, "Oba-san is Rias not coming?" Venelana gave a sad smile and said, "Sorry Sona-dear she had a fever, so she is unable to visit today." Sona gave an understanding nod and thought, 'Great!!! now she won't learn about Tatsuya, I was kinda worried about their meeting but it seems like that it will not happen anytime soon.'
Tatsuya who heard this thought, 'Whoo hop! my plan worked I don't have to worry about anyt-' Just as he was about to continue thinking a bright orange magic circle formed in the room with fire coming from it. Seeing the circle all of them looked at each other and Tatsuya thought, 'Why does my situation changed from 'Bad' to 'Worse''
