The god Miku mentioned is most likely [Phantom].
"..." Listening to Miku's narration, Katsu lowered his eyes. He had nothing to say about the gods Miku mentioned. He already knows the plot of this world so he knows who [Phantom] really is, but there is always some difference in each world, he came so he can't be sure what changes in this story the worst case is that he can't convince [Phantom] and have to fight her himself.
"I understand your mood very well." Katsu's voice was a little low, with a cold light shining in his eyes.
"Understand? Oh, don't make people laugh! Why do you say you understand when you haven't experienced this?!"
"...Yes, I have never experienced it, so I am not qualified to say that I understand - what you have experienced is nothing more than betrayal, but I can let you see my memories to prove that I will never betray you" Katsu revealed a smile said with a confident tone.
With that said, Katsu reached out his hand to his waist-length hair, and then in Miku's disbelieving eyes, he disabled Mana's spell, revealing the short and medium hair below, which was no more than shoulder length.
The atmosphere was somewhat solidified.
"You… …"
"Yes, I am..."
"Don't you look good with short hair? Why do you wear a wig?"
"..." Katsu suddenly didn't want to talk to Miku.
A staff appears in his hand and points at Miku's head.
"This is..." Miku said in surprise, she remembered this stuff was from a girl she met at the arena with a boy.
"Don't resist, this will allow you to truly understand me ---"
… …
A minute later, Miku lowered her head and panted heavily.
What is this?
Is it this person's past?
At this moment, Miku no longer paid attention to Katsu's gender issue. What she had just seen was enough for her to ignore such things.
… …
"How about it, do you think I can understand your feelings now?" Katsu opened his mouth and said with a smile. The memories he gives her are from when he first came to this world every of his actions are recorded but only his interactions with the systems are hidden.
"...This kind of thing... Who knows if you made it up..." Miku, who finally recovered from the scene she just saw, looked at Katsu and said stubbornly.
Katsu didn't speak, just looked at Miku quietly.
Three seconds later, Miku looked away with a lack of confidence. She actually still knew clearly in her heart whether those things just now were true or not...
"Ha... now that we understand each other, right? Do you think we can become friends?"
This time, in the face of Katsu's inquiry, Miku was silent. After a long while, she said in a complicated tone: "Even...even if I approve of you, I will not approve of other people. With such power how could a creature like you a human being, which is self-interested at the expense of others, have people like you..."
"I'm a human, that's what I think..." Katsu sighed.
"..." Miku said nothing, but looking at her expression, it was clear that she did not agree with Katsu's words.
Shaking his head, Katsu took a step forward, came to Miku's bed, and asked, "Do you mind if I sit down?"
"Whatever." Miku glanced at Katsu and said calmly.
Before, let alone let a man sit on her bed, even if a man talked in front of her, she couldn't help feeling sick! Of course, it's the same now, but Katsu is a little special in her heart. He's not considered a man when he crossdress... ahem, it's better to say that he is the only man she approved.
Of course, not knowing what Miku was thinking, Katsu looked sideways at Miku in surprise, and then unceremoniously sat down on her soft big bed.
"From now on, we are considered friends, right?"
"Whatever you think."
"Yes---then as your only friend, I have the obligation to save your worldview and values."
"..."
"Well--before then, I will always dress up as a woman and accompany you to school."
"..."
"Well - and, aren't you afraid of humans? Humans are also divided into good guys and bad guys. From now on, I will be responsible for helping you get rid of the bad guys. Sooner or later, you will willingly return to the human group."
"Who is afraid of humans!" Miku didn't remain silent this time.
"Well, it seems I was right." Katsu looked at Miku with the corner of his mouth raised slightly.
"You!"
"I didn't say anything."
"You guy!"
"Ha ha ha ha---"
"Pfft..."
… …
Time passed slowly, and before they knew it, it was already late at night.
During this period, he was finally able to communicate with Miku normally, he didn't know how many times, tears of laughter flowed down.
Looking at Miku who was wiping the corners of her eyes, Katsu felt slightly relieved, and then smiled casually: "How does it feel to open your heart and chat with others?"
"...very happy."
Hearing this, Katsu couldn't help but smile and said: "Right, right? So, you have been too tired before, so try to open your heart and communicate with others..."
"It can't be done!" Miku interrupted Katsu: "You are special... I don't think there is anyone like you among humans..."
"..." This time it was Katsu's turn to be silent. Part of his memory also has Shidou but, apparently, Shidou is not up to Miku's standard.
After a while, Katsu looked at the night sky outside the window, then sighed and said: "Okay, it seems I'm impatient... That's it for today. It's already very late, I'll go back first."
With that said, Katsu stood up and prepared to leave.
"Wait a moment."
"Huh?" Miku suddenly called out, and Katsu looked back at her in confusion.
"You said you would continue to go to school with me, right?"
"Ah, after reading my memory, you should know that I am a person who abides by my promises."
"..." Miku was noncommittal if what she saw was true. Even a bit jealous watching the other spirits having fun with him.
"So, goodbye."
"Wait a moment!"
"What's wrong?" Katsu rolled his eyes, then turned around again.
"Are you called Mitsu or Katsu?"
"..." As if he didn't expect to hear that name again, Katsu was obviously stunned when he heard the words, and then chuckled: "I am Mitsu, and I am also Katsu."
"Then I'll continue to call you Mitsu-chan~"
"Well, you can do whatever you like with this kind of thing." Katsu shrugged and said with a smile, "See you again this time."
"Well --- see you tomorrow."
