Grimm's face is a skeleton, so he can't understand his expression.
　However, perhaps because of his relative relationship with Grimm, the pair of oves showed him somewhat tired.
　Ray could understand why he was tired, but that's why I think it's more likely that Grimm was involved in the Trent forest incident.

"Well, what do you want? 儂 is busy in his own way right now."
"Are you busy, after all, with that particular material?"
'Well, that material has some interesting properties. Now we're looking for other special properties.'
"I suppose,"

　Grimm obtained material for a giant eye monster.
　It wasn't just an eyeball, it had countless tentacles around it, and even a tail resembling the optic nerve behind it.
　They are monsters who exist outside of this world, who have the ability to create cracks in space and interfere in this world, and who even have the ability to produce and summon monsters in large numbers by sacrifice.
　Fortunately, the red cloths were sacrificed during the Reyes' time, and perhaps because they were low-quality sacrifices, they were monsters of the size of Cobort.
　If a high-ranking adventurer or notorious person had been sacrificed, what kind of monster would have been called?
　With that in mind, Ray is still wary of them now.

"Anyway, that doesn't matter... but I contacted you because I wanted to ask you something about it. I contacted you the day before yesterday, but it didn't connect at all."
'I see. I'm a little absorbed in my research. So why on earth did you contact 儂? There's nothing I can say about that eye-catching material, because there's still a lot I'm studying?'
"No, no. ... It's not that I'm not interested."

　As soon as he says no, Ray says he's not in a hurry to see Grimm look disappointed.
　I didn't know if I believed Ray's words or if the expression of regret was the performance itself, but Grimm looked up and spoke.

'Well, if we talk about it later... what on earth would you like to know?'
"Actually, a few days ago, in the forest of Trent near Gillum, green people with green skin, hair and even blood, and lizard men who were hostile to the green people, had the ability to interfere in space, so I thought maybe this was the result of his experiment."
『……』

　Such Rey's words silence Grimm for a few seconds.
　Ray didn't know what the silence meant, but he continued.

"And what do you think? Do you have any idea?"
'Well, I'm sorry, but I don't know about it. We haven't conducted any experiments that would affect it so far.'

　For now, perhaps, it means that in the future... we intend to do such an experiment in the future.
　But if it doesn't work against me, Ray has no intention of saying anything about it.

"And as for the Greens and Lizardmen who have been metastasizing for the last few days, you mean Grimm has nothing to do with them?"
"Well, I'm sure, sir. . . . . . . . . . . . . . . . . . . a green man?"

　Grimm suffers from Ray's description of the green man... and what he is like.
　Not only Ray but others, including Elena, were surprised at the appearance of Grimm on the paired oven.
　The Grimm, who has the capacity to call it Rich Road, has lived since Zepail was alive... and it may be true that it exists because it's undead, but anyway, there's nothing I don't know about this world's events... because I thought there was very little I didn't exist.

(Did my intuition that Grimm had transferred from another world proved right? Well, I don't necessarily know much about other continents.)

　Ray looks at Grimm and opens his mouth.

"Oh, Grimm. Hasn't Grimm ever heard of a green man?"
'No, no. At least it is not a race that exists on this continent.'
"...is there a race that does not exist on this continent?"

　As he says so, Grimm pauses for a moment and turns a sharp glance at Ray.
　Exactly, Grimm doesn't have eyeballs, but it's true that he still felt a strong stare, even though it's across pairs of ovens.

"What!? ... And what do you think? Do you think it's possible?"

　Despite Grimm's gaze, Ray asks Grimm nothing more.
　Grimm on the other side of the pair's oven took such a close look... a few seconds, or more than ten seconds.
　utter after that silence

'There's no possibility, I'll say. There's no way to come into this world from another world, as you can see when Ray comes into this world.'

　At Grimm's words Ray still looks convinced.
　Contrary to Ray, each of the three women looked surprised.

"Is that... really true?"

　Elena asks Grimm unconsciously.
　The other two had similar expressions on their faces, albeit in silence.
　Even if you know Ray, you can't believe he comes from another world so easily.

"I can't say for certain, for he didn't see the man in person."
"But there was a lizard man, let alone a green man, but is there a lizard man in another world?"

　Following Elena, Marina expressed her doubts.
　It would have been hard to believe that there were the same monsters in another world.
　However, since the Zozo have the intelligence to make a country, it's not the same as the lizard men in this world.

'It's not impossible... but... Ray. Was there a lizard in the world where you were?'
"No, I don't. On the contrary, there are no elves, no dwarves, no beasts, no magic at all. ... No, maybe there was magic, but at least I don't know."
"Ho" (literally, "ho" in Japanese)

　Grimm exclaims interestingly, perhaps unexpectedly, that the difference was so different.
　Unlike Grimm, Elena, Marina and Vihela don't seem particularly surprised.
　Maybe it's because they've all heard from Ray about the world he used to live in.
　All three of us, however, were surprised when we heard about the world from Ray.

'Is there no lizard man in the world with Ray? ... But there are countless worlds in the world. Then there could be a lizard man in the world.'

　Parallel worlds, parallel worlds. That's what Ray recall.
　For example, the world where Ray ate bread for breakfast and the world where he ate fried udon.
　The world branches off in such a myriad of ways...

(No, the concept itself is different when it's parallel to another world.)

　Suddenly, I think so.
　Ray's knowledge... that's what I learned from comics, anime, games, novels, and so on when I was in Japan, but I understood that the parallel world is different from the other world.

"Anyway, it's a little hard to explain, but when you think about it in a way that I've done, it's like the lizard men are from another world."
'Well, I can't give you a definite reason, but will that be the case? ... Well, it's a little interesting. It's just Ray's the sixth sense.'"No, even if it were to be amused... by the way, it was Grimm's work... no doubt that it was not something to do with some experiment?"

　Feeling that if things went on like this, the story was going to get off the track, Ray asked Grimm again... and finally, to confirm it.

'Well, I'm investigating that eye-catching material, and I'm doing some light experiments, but it's not the first time I've ever had that material, so I can't deny that it's had some effect on me without my knowledge.'

　Grimm's words, saying so, did not seem to lie.
　For those who don't know anything, it's no use thinking about trusting the undead so much.
　But for Ray, Grimm is undoubtedly a reliable partner.
　In fact, I've been helped many times.

"Well, then, for the time being, we may think that the material that Grimm brought has nothing to do with this case."
"Ray, why don't you ask about that?"

　Suddenly Elena tells me that Ray is disappointed.
　Since there are a lot of things Ray is having, I can't understand that.

"About what?"
"I can't understand the language. We can't do anything other than teach them the language..."

　Elena pauses and looks at the Grimm on the pair of oves.
　We can't do anything about it ourselves, but Grimm could do something about it.
　It was obvious that he was saying so.
　Ray understands Elena's opinion, so he nods a little and then talks to Grimm on the pair of oves.

"Hey, Grimm. Actually, I'm a lizard and a green man who's been transitioning, but I don't understand this. So communicating with them is a gesture. I'm teaching them a little bit... but I don't know when they'll actually understand this."
"Well, not only the lizard man, but also the greens don't understand the language?"
"That's true. I think both races are probably speaking the same language..."

　The Greens and the Lizardmen are not necessarily speaking the same language, as long as they can't communicate.
　But for Ray, who often interacts with both races, I understand that they are probably the same language.
　...and it seemed to me that there was communication between the Greens and the Lizzards.

"Well, ... wait a minute,"

　When he says so, Grimm disappears in front of the pair of oves.
　Ray could have guessed that he had gone looking for something.
　It meant that Grimm could change the status quo in some way... specifically, it was more likely that he had something to understand the words of the Greens and Lizardmen.

(If I knew that, I'd get in touch with Grimm sooner... oh, no. I can't. Anyway, if I contacted him yesterday or the day before yesterday, he would have worked hard on his research.)

　Ray's idea is correct, as he actually tried to contact them using a pair of oves, and it didn't work.

"I think we'll get by with this,"

　Marina's words nodded in agreement with others.
　Even though you can see Zozo following Ray, there are many problems with his inability to communicate.
　That's why it's so helpful that Grimm has prepared some kind of magic item or something."

"What do you think it is? I think it's a magic item."
"That's probably true. Isn't it the magic item that matters?"
"Well... bracelets?"

　Vichela tells Marina so, but Ray shakes his head.

"If you're going to be able to speak, don't you need it near your mouth? Then, necklaces, earrings, collars... That's what it is?"
"'That's the way out,'

　The denial of Ray's words was reflected again across the pair of oves.
　There was a slab in the hand that was large enough to hold it in both hands.

"And?"
"Well, a little while ago... maybe a hundred years ago. It's a magic item I found in a dungeon that deep down. It's something that senses the will of the user and displays it as a letter on this tablet. It seems that it was used by someone who couldn't speak..."

　I see.
　Ray nodded in obedience to Grimm's words.
