When Tauro returned from the dungeon, he first went to the Adventurer’s Guild and reported that he had made a slime into a familiar monster.

The receptionist, Ryuko, registered it as a familiar.

“It seems that it is very rare for people to register a slime as a familiar, since they are all treated as disposable slimes.”

She told me.

It is true that an ordinary slime cannot even move, and the tamer has to carry it along.

The slime is not worth the trouble.

So it was natural that no one would report it to the Adventurers’ Guild because it would be quicker to break the familiar contract right then and there.

“So, where is this slime? It’s a living creature, so it shouldn’t fit in Tauro’s magic storage, and it’s too small to fit in that pouch on your waist…”

Ryuko, the receptionist, looked around Tauro for confirmation.

“Pella, break out of your mimicry.”

As Tauro said this, the surface of his leather armor rippled and Pella, a subspecies of the Slime Emperor, suddenly appeared in front of Ryuko, the receptionist, like a magic trick.

“Eh!? Could the slime be the mimic slime that was reported to have been discovered in the depths of the dungeon long ago?!”

Ryuko was surprised by the slime that suddenly appeared in front of her, and she immediately performed an appraisal of the monster.

“──!? It’s a mimic slime with appraisal inhibiting skills? This is a new species! Tauro-kun, where did you find such an amazing slime ……, and how did you manage to tame it ……? Huh? Tauro-kun, did you have the ability to use monsters?”

The receptionist Ryuko is currently the only adventurer in this Dragon Tribe Village branch・Adventurer Guild, Tauro’s ability has been informed to some extent by checking the tag and identity verification.

There must not have been any monster users among them.

‘That’s because I learned it in the dungeon ……. After that, I ran into this Pella in the deeper levels, so I just tamed it.”

Tauro laughed a little and said while stroking the belt.

“…… I see that you did. ……. Did you say deep layer? I heard that mimetic slime appears after the 150th level, but did you try to see if you could make it to that level? No, Tauro-kun, you shouldn’t do such a dangerous thing! I don’t mean to put it this way, but the members who followed Tauro-kun today are still novices compared to the dungeon capture group, and they could have been wiped out at the 150th level, which is a dangerous level, you know? Anyway, I’m glad you’re safe and sound. ……”

Ryuko, the receptionist, warned Tauro and was relieved when he pointed it out.

“……Ah, I’m sorry. I did not know the adjustment and went to a deeper by mistake ……”

The truth is, he had gone as far as the 201st level, but Tauro kept his mouth shut about the important parts, thinking that she would be incredibly angry if he said he had reached the 201st level, given the level of anger she was getting at the 150th level.

“……But still, you really were able to tame a mimic slime, weren’t you? You’re very lucky because there are probably no examples of people being able to do it. The “monster Mastery” that Tauro learned must be of a very high level. Otherwise, the probability of being able to tame would be extremely low.”

Ryuko, the receptionist, was impressed.

“From what I’ve heard, it is the most rudimentary ‘slime user’ among the monster tamers”

Tauro answered casually.

“Eh!!? Tauro-kun, slime users have a 99% taming rate against normal slimes, but it’s almost impossible to tame against mimic slimes, you know? Do you know how lucky you were!?”

Receptionist Ryuko shouted again in surprise.

It was loud enough to echo through the Adventurers’ Guild, but there was no one there but the two of them, so there was no need to be shy.

‘…… it seems so. Haha …….”

Tauro laughed and shook it off, swallowing his words without being able to say that it was actually not a mimic slime but a variant of the Slime Emperor, so perhaps the probability was even lower.

“─ ─ You are being too reckless, Tauro-kun. The dungeon is a place where the difficulty of conquering it can suddenly increase just by going one level deeper. The 150th level is a dungeon that only the attackers and their supporters dive into. In such a place, today’s members at the escort level could have been wiped out, so you should not carelessly leave the break room. I’ll report this to the chief, but we must be careful from now on!”

After a stern lecture from Ryuko, the receptionist, Tauro apologized and went back to Drago’s house, where he would sleep for the rest of the day.
