Since Hajime didn't know whether Shia was simply staring or if she was having at argument with it. However, when sweat lines started to appear on her face and she didn't reply to him, or when he talked to it in the normal way, he used "Telepathy" instead.
"You, can you really use telepathy? Can you really converse? Can you understand my words?"
Because of the sudden telepathy, Lehman's eyes twitched for a moment in response. It followed by shifting its gaze from Shia to slowly looking at Hajime. Shia whose expression expressed, Somehow I won!, was ignored.
"... Tch, this should be our first meeting. First, introduce yourself. That is how you show your manner. Good grief, this is why the young people these days..."
He was taught about manners by the fish with a face of an old man. He regretted his mistake. With cramped cheeks, Hajime tried to talk again.
"... My bad. I am Hajime. Looks like you really can converse. Just what is Lehman?"
"... You know. Just what is human? How can you answer that? That's why, how would I know the answer. Well, I only can say I am me. No more no less. Also, call me by my name or whatever you like."
Hajime had thought, "Just how does it think..." But somehow it spoke about common sense, moreover it was rather cool. That was completely unexpected. Wasn't it written that it was unmotivated?, he wanted to complaint to the aquarium's staff. Hajime was slightly looking at the distance in escapism, but this time a question came from the Lehman.
"I also want to ask one thing. You, why can you use telepathy? There's no sign of the use of human's magic... It was as if you are the same as me."
It was nothing but a natural question. After all, a human was using the peculiar magic, "Telepathy." It was curious as to why he was able to casually use just like it. It might be the cause of why the rarely talkative Lehman was responding to Hajime's conversation. Hajime explained he was able to use it by eating the demonic beast that was capable of using telepathy.
"... That's a lot of hardships for someone so young. Okay, ask me anything you want. This old man will answer anything in my knowledge."
He was sympathized. Apparently, it thought he was so poor that there was no choice other than eating the demonic beast. When it saw his current appearance and he was wearing good clothing, it said as it sniffled, "Looks like you've worked so hard, good boy! It make me want to cry."
Hajime didn't correct it because it was the true he had some hard times. However, for him to be sympathized by a fish... it was somewhat depressing. He somehow managed to set it aside and asked Lehman various things. For examples, Does a demonic beast have a clear will?, How were the demonic beasts born?, Are there any other demonic beasts people can communicate with?, ... Lehman answered that most demonic beasts didn't have clear will. It didn't know any other demonic beasts that could understand human language other than its species. Moreover, it didn't know how the demonic beasts were born.
Moderate amount of time had passed as he asked a lot of things, and they began to gather attention because it was a surreal spectacle for the onlookers to see a young man and a fish with a face of an old man staring at each other. Shia, who began to feel restless, was tugging Hajime's sleeve, so Hajime rounded up the conversation.
Even though his conversation with Lehman was somewhat interesting, today was decided for him to go out and spend it with Shia. He would not neglect his promise. Lehman also said, "Oops, looks like I have obstructed your date," as it rounded up the conversation by reading the mood. By the way, they got along so well that they called each other with "Leh-san" and "Ha-boy." Hajime could see the "nobleness" inside the Lehman.
