That's what Shester said as she nodded, Melba said as she leaned her neck slightly.
"What's one going to do now? There should be four tattoos in all?
Shester answered Melba's question with a little thought and face.
"Um. As for the fourth, honestly, we barely have any information. All I know is that my mother is apparently a discriminated citizen from the Kant continent. What do you say, by the way? Don't you have any information about a fourth person?
Then Melba shook her neck wide and sideways.
"No, nothing. As much as I honestly doubt its real. What do you think, actually? Is there really a fourth person or something?
"I don't have enough information to assure you I'm here..."
Melba thought to Shester's answer, hands on his chin.
"... I mean, you're expecting that, too, and you're talking about matching the tattoos for the three of us, right?
Then Shester waved lightly.
"Well, yeah. If a tattoo for three completes the map, you won't have to look for a fourth. But if it's not complete, if that incomplete map gives you some idea of where the stash is, you can go and find it. I think it's a good idea to go look for a fourth person again."
Then Melba responded with a difficult face, keeping her right hand on her chin.
"... I see. That's a good idea. By the way, what kind of substitute do you imagine a hidden treasure to be?
