Chapter 657 A Son Cannot Defeat His Mother
Chapter 657 A Son Cannot Defeat His Mother
Edited by: Kanaa-senpai
Despite the sudden intrusion of telepathic thoughts, Shinji’s expression remained as cool as a mountain spring. Inside, however, a wave of guilt washed over him. Because of his very presence, the confidential strategy meeting was being broadcast directly to the side of the Demon King, or more specifically, to Lechary¹.
Had he not been there, the demons would never have been able to eavesdrop with such pinpoint accuracy. Yet, he reasoned with himself, without his strength, the resistance’s battle was already a lost cause. He hoped the scales would balance out to zero in the end.
’By the way, I wonder why Jin-kun and Freri-chan are over here? This is the Outer World, isn’t it?’
Shinji understood immediately that his foster mother meant a world outside the jurisdiction of Arian², the goddess who managed their own realm. He decided there was no use in hiding the truth and sent his thoughts back.
’We’re acting as Apostles³ of the goddess due to certain circumstances. We came here because a request for reinforcements was sent out.’
’Oh, how wonderful! Just as I’d expect from our son! To be entrusted with a mission to the Outer World… you’ve certainly polished your skills in such a short time.’
Just as his foster father had mentioned during their earlier reunion, the couple had expected to see Shinji much later in life. For Lechary, this encounter was a delightful, happy accident. However, the cheerful tone of her mental voice suddenly shifted, taking on a more complicated edge.
’That means you two are my enemies now. Oh dear, what shall I do? It’s quite a pickle. Your mother is currently in the middle of playing with the Demon King, you see.’
’I met Dad earlier, so I’ve heard the gist of how things are going.’
’I see. And was Yana-kun doing well as a fuel tank?’
’Is that really the way to ask about him? Well, he was perfectly fine. Honestly, I’m more surprised that he managed to get caught in the first place.’
’As Yana-kun might have told you, it was mostly a matter of poor compatibility. And perhaps something to do with being a long-lived species… but let’s not change the subject! So, what’s it to be? Do you want to try fighting your Mother?’
Her mental voice returned to a bright, airy tone. Shinji could easily picture her standing there with a beaming smile, yet he knew he had to tread carefully. The fate of their world rested on this very dialogue.
’If it comes to fighting you, Mother, I’m pulling out. I make it a point never to start a fight I can’t win.’
’Eh? You’re going home? Already? But we only just met! I want to hear all about how you became an Apostle!’
’I’d love to talk, but we both have our positions to consider. It would weigh on my heart if you were punished later because of me.’
’Oh, stop it! Pretending to be kind just to squeeze out a concession. Jin-kun, you really are a cunning one!’
Normally, having one’s ulterior motives laid bare would cause irritation, but Lechary seemed to take it as a compliment. In her eyes, it was proof that her foster son was growing up to be a true Succubus⁴. She continued her telepathic chatter, sounding quite pleased.
’The Demon King doesn’t necessarily want this world at any cost. This is just a way to kill time. So, even if the suppression fails, it’ll be fine. He’ll probably just use it as another excuse to humiliate me.’
’So you’re actually aware that you’re being humiliated…’
’Of course I am. It wouldn’t be exciting otherwise!’
Shinji felt a sense of inevitable resignation. He knew his own tastes were somewhat warped, but they seemed positively ordinary compared to his foster parents. To any third party, however, they were likely two peas in a very strange pod.
’Back to the point. The goddess told the Apostles to destroy the altar and block the path. It seems she intends to send the survivors back to their original world after a ceasefire.’
’Hmm, in that case, I’d like you to hunt down all the monsters I brought along. I’ll just make up a story that the altar was destroyed while I was busy fighting—or should I say, playing—with Jin-kun.’
’If that’s the plan, I’d appreciate it if you kept the monsters from leaving the capital. When we launch our assault, we intend to wipe out every monster in the town. I think we can manage it if you don’t interfere, Mother.’
’Okey-dokey! Let’s go with that. But… if we leave it like this, only Jin-kun gets what he wants. I think Mother deserves a little favor too, don’t you?’
’Of course. We need a condition that satisfies you as well.’
As expected, she wasn’t going to make it easy. Still, he had achieved his primary goal of avoiding a direct confrontation. Judging by Lechary’s tone, the resistance forces under Luluane should be able to handle the monster hordes within the city streets.
With the destruction of the altar and the defeat of the monsters within reach, the reward from Goddess Padra⁵ was almost in his grasp. To secure it, he had to fulfill his foster mother’s request, no matter what it was.
Shinji had braced himself for a request for a mock battle. He assumed she would want to see the growth of the son who now possessed the potential to defeat her. But the reality was quite different.
’Then, until I go back, I want you to call me “Mama” just like you did when you were a little boy!’
’…Mother, there’s a limit to how much you can mess around…’
’Mama.’
’…’
Shinji did indeed have memories of calling them ‘Mama’ and ‘Papa’ shortly after they had taken him in. But he had long since outgrown those terms. For a man with a pregnant wife, it was a word that felt heavy with embarrassment.
Yet, it was a masterfully balanced demand. Had she asked him to speak like a toddler, he would have refused instantly. But just the name… it didn’t kill his dignity, it merely tickled his sense of shame. It was a line he could just barely tolerate. To anyone watching, this uncanny ability to find the exact point of compromise proved they were parent and child, blood or no blood.
Right on cue—or perhaps at the worst possible moment—the council’s discussion turned to who would face the demon reflected in the sky.
It was only natural to pit the strongest against the strongest. Every eye in the room turned toward Shinji. Though he was still wrestling with his internal conflict, he gave a firm nod.
”Leave it to me,” Shinji said. “I will handle the demon. No matter what happens, I’ll keep her occupied, so I’m leaving everything else to you.”

His steady demeanor in the face of such a formidable foe inspired confidence in everyone. Luluane, Tiana, and Tiona were no exception. Unaware of the behind-the-scenes negotiation, the dire situation made their hearts flutter more than usual.
”…Please, Shinji-san,” Luluane said, her voice filled with absolute trust.
’The Apostle…’ Tiana thought.
’I must ensure that Shinji-sama remains in peak condition…’ Tiona thought.
The devotion of the disciples swelled. With the atmosphere now thick with expectation, Shinji knew there was no turning back.
’…Fine. I won’t change the way I speak… but I’ll do it, Mama. Please go easy on me.’
’Yes, yes! While we’re pretending to fight, you can tell Mama everything that’s happened until today!’
Swallowing his pride, Shinji chose the path of practical benefit. Freri and Lechary both looked quite satisfied with the rare spectacle of Shinji’s prolonged internal struggle.
’He said “Mama.” …How amusing,’ Freri thought.
’Freri-chan, you can call me that too, you know! “Mama” has a much nicer ring to it than “Auntie”!’
’Understood. Mama,’ Freri replied.
’Freri, you have your own mother, don’t you? Aunt would be so sad if she heard this—’
’It’s Mama, right?’ Freri asked. ‘I’m calling her Mama.’
’…So I’m not the only target. Fine, fine. You’re Freri’s Mama too, then.’
When double-teamed by the two of them, Shinji had no choice but to wave the white flag. Yet, this kind of banter was something only a family could share. Despite the lack of blood relation, it felt nostalgic and surprisingly pleasant.
’At any rate, the biggest obstacle has been dealt with,’ Shinji thought. ‘Now I’ll leave the rest to Luluane and the others. I just have to make sure the final battle at the capital doesn’t look like the farce it actually is.’
It was clear that Luluane was no good at deception. Realizing it would be impossible to keep pulling the wool over the eyes of Goddess Padra, who was watching everything unfold, Shinji asked Freri to act as a mediator to help smooth things over.

Summary:
Shinji engages in a secret telepathic negotiation with his foster mother, Lechary, who is leading the demon assault. They agree to a staged battle to allow Shinji to destroy the altar and clear the monsters without a lethal confrontation. In exchange for her cooperation, Lechary demands that Shinji call her ‘Mama,’ a request he reluctantly accepts. The resistance members, unaware of the deal, are moved by Shinji’s bravery in volunteering to face the ‘powerful’ demon alone. Shinji realizes he needs to maintain the appearance of a serious struggle to deceive both his allies and the goddess Padra.

Character Insight:
This chapter highlights the unique ‘family’ dynamic between Shinji and his foster parents, showing that despite their disparate roles as ‘Apostle’ and ‘Demon,’ their personal bond supersedes political or divine alignment. Shinji’s willingness to sacrifice his ‘dignity’ by using childish terms of endearment demonstrates his pragmatic nature—he values the safety of his allies and the success of the mission over his own ego. Lechary’s behavior confirms her mischievous and unconventional affection for Shinji, treating a world-ending invasion more as a playground for family interaction than a serious military conquest.

Behind the Scene:
The title ‘A Son Cannot Defeat His Mother’ refers not to a lack of combat prowess, but to Shinji’s inability to win against Lechary’s emotional manipulation and specific demands. The chapter plays with the contrast between the high-stakes ‘Capital Battle’ and the ‘farce’ taking place behind the scenes.
