Start by Eating Jake Jake no Mi

"...." 

Ravel, Asia, Misla, and Serafall stared at Masa in a daze as they saw him eating a lot of food, the chefs continuously cooking him food, and the maids serving him all of it. Still, at the same time, they could also see his improvement, from being thin and weak to his optimum state, healthy, and compact muscles. 

Nevertheless, everyone had to sigh, thinking that he was as handsome as ever. 

Even if he was thin before, he appeared like an elegant scholar, yet now, he had become the manliest man with powerful muscles. 

Serafall thought that Masa really had grown, and he was no longer a tiny cub that called her "Onee-chan" but a great lion that could even impregnate her! 

'Unfortunately...' 

Serafall bit her lower lip in frustration when she noticed Misla's gaze in her direction. 

Yes, if there was a reason why she couldn't approach Masa and do something that she wished to do, it was all due to Misla, who kept watching her. 

'Even though you wish the same...' 

Serafall pouted, causing Misla to look away. 

Still, the interaction of the two aside, Asia and Ravel looked at him worriedly. 

"Are you okay, Masa-sama?" 

After coming to the Underworld, Asia was easily accepted. Not only due to her kind nature but also because her ability made her important in his family. 

Healing abilities were rare, after all, and even if a devil could recover faster, it didn't mean that they could heal instantly, so there was no doubt that having Asia, who could heal others instantly during a critical moment, was a great thing. 

Everyone thought that Masa had made the right choice to choose Asia, and as he was the first woman that was chosen, there was no doubt that she was special. While others wouldn't think that she would be his official wife, she was just slightly below, and that was why everyone respected her. 

Or rather, after Asia came to the Underworld, Misla quickly took her in, trying to teach her about the knowledge and her duty, which included... anyway, let's talk about that problem later. 

"I am fine. Thanks for the food." 

Masa let out a comfortable sigh, then looked at Ravel, who had helped him before. "Thanks for the Phenex Tears, too, Ravel." 

"Hmph! Don't do something so dangerous again!" Ravel's eyes were still red when she recalled Masa's previous state. 

"That's the last time." 

Masa said so, but he didn't make a promise since he didn't think that it would be the last time for him to risk his life to become stronger. After all, the higher the risk, the higher the return, right? 

Yet, with his current defense, it might be hard for one to hurt him, he thought. 

"Thanks for healing me too, Asia." 

"No, it's fine. I am glad that I can be of help, but Masa-sama, as Ravel-sama said, please don't do something dangerous again, okay?" 

"...." 

Masa was glad that they were worried about him, but then again, he felt like he was being spoiled somehow. Still, he had to say Asia could easily join everyone, and even Misla and Ravel didn't scold him for bringing her and quickly accepted her. 

'If it's Raynare, Kalawarna, and Mittlet.' 

When Masa thought of the three, he was sure that his house would be in chaos, so there was no doubt that he was glad to accept Asia. 

Still—

"Hey~! Hey~! What about me~? What about me~? I have come during my busy schedule to meet you, you know~? Masa-chan is so cold~! I am going to get angry~! Hmph~! Hmph~!" 

"..ah, um, thanks, Serafall-sama." 

"Onee-chan~! Call me Onee-chan!" 

"Ah, yes, Onee-chan." 

"Good~! Masa-chan is the sweetest~!" Serafall quickly jumped onto him and hugged him tightly, causing the three to look at her in jealousy. 

Meanwhile, Masa could feel Serafall's sweet scent and softness on his face, which caused him a natural reaction. 

"Eh?" 

Serafall was startled, then noticed Masa, who could only lower his head awkwardly, causing her to laugh. Yet inwardly, she was dumbfounded and blushed red at how humongous it was. 

'This... Masa-chan has really grown up!' 

Still, while Ravel and Asia couldn't say anything to Serafall due to the difference in their status, Misla was different since even though she was away, she was still the wife of the head of the House of Bael, who was the Great King of all the devils, which meant, she was the queen of the Underworld. 

"Serafall, I think that you should let go of him." 

"Eh? It's fine, isn't it? It's been a while since I met Masa-chan, after all, Aunty." 

"...." Misla. 

Yes, compared to Serafall, Misla was a little older, even though their age didn't appear much different. 

Yet, there was no doubt being called an aunty by Serafall felt weird! 

Or rather, they should be from the same generations! 

If Serafall married and had a child, then her children would be about the same age as her son, Sairorg, but Serafall didn't marry nor did she have any men, so how could Misla feel comfortable when her nephew, whom she treasured much, be married to someone around her age? 

More importantly, if Serafall really did it, then her feelings that Misla had tried to suppress wouldn't be able to be stopped anymore. 

"By the way, don't you have a job, Serafall? I think that you should leave now, especially since you have stayed so long." 

"Ah, no! I don't want to go to work! I want to stay with Masa-chan more! I want to stay with Masa-chan!" 

Clinging to Masa tightly, Serafall didn't let go of Masa. Still, she had to say that Masa was really tall, yet it was okay since she felt that it was nice to have someone huge as it felt like she was dominated. 

'More importantly...' 

While it was her guess, Serafall could feel that Masa had become much, much stronger. 

If possible, she wanted to have a spar with him, and when Masa won, then—

"You are a Maou Leviathan! How can you leave your job like that? Hurry up and go back!" 

Yet, Misla hadn't given up on separating Serafall from Masa! 

Still, Serafall snorted inwardly and loosened her arms around Masa, which caused Misla to see the stiffness in Masa's lower body. 

"—?!" 

Watching this reaction, Serafall snorted, thinking that Misla was a hypocrite for playing the role of a strict yet caring aunt for Masa when the truth—

Still, Misla quickly calmed down, pulling away Serafall quickly, then covered Masa's stiffness with a cloth so it wouldn't be seen by Asia and Ravel since she felt that they were a little too young, but when she hid it, her hand held the stiffness carefully as if trying to measure his growth. 

"....." Masa. 

"Anyway, come on! You have stayed here for so long! Your followers are going to be crazy!" 

It was just a moment, and as if she didn't do anything, Misla pulled away Serafall and brought her outside to meet all of her followers who had been waiting for her. 

"Ah, no~! I don't want to go to work~! Masa-chan, help me~!" 

However, Masa hadn't recovered from Misla's act since he didn't expect his aunt to do that to him. 

'Did she think that I am that boy who hasn't grown up? Or was it an accident?'

'This must be the reason,' Masa thought. 

Frankly, Masa had been taking a bath with Misla until fourth grade before he stopped accepting her invitation since he was afraid to get stiff. It was hard for him to see her as an aunt or a family member, especially when she was so charming and often washed him on that area too carefully with her white and smooth hands, which made it even harder to calm down. 

Still, in her eyes, Masa knew that he was just her nephew, and she was also the mother of Sairaorg, so how could he betray her with his dirty thoughts, right? 

However, once again, Masa was no longer a cub, and it was impossible for him to remain indifferent to Misla's act. 

Nevertheless, he tried to calm himself since he knew that he had to comfort his childhood sweetheart, who pouted and looked away from him.
