I have the answer already in me but I still don’t have concrete evidence. I asked Reus to become the interpreter and then I asked the Hundred Wolves.
“Where did I bury a hidden treasure?” (Sirius)
“He said… ‘at the root of the tree in the garden’.” (Reus)
“If I throw a branch and enjoy myself, what will we found?” (Sirius)
“Bear? ‘I found a nest and chased by parents’. What is Bear, Aniki?” (Reus)
“I will tell you later. Then, next is…” (Sirius)
I just asked several questions and the answers didn’t changed from my memory.
For memory and identical movement, there were various memories that only we know.
I cannot remember the name anymore but… I have no doubt.
“Your name is… aren’t you?” (Sirius)
“Woof!” (Hundred Wolves)
When I was trained in the previous life by Master, I picked a dying puppy in the rain.
That puppy was somehow recovered and became my first family, I trained it and it became my partner while being trained. And then, it died sometime after I became an agent.
There are many questions that came into my mind like why was he in such place and why does he have that appearance but I had heard the things I wanted to hear in those days.
“Say… were you happy?” (Sirius)
“Woof…” (Hundred Wolves)
“He was happy. And he said, he was really happy for meeting you again… what is this, Aniki!?” (Reus)
His habit when he is happy doesn’t change at all where he brings his face close to my chest. There was a bit irritation since I couldn’t call his name but I hugged my partner’s face that had become much bigger than before.
“Aah, I’m also glad to see you again.” (Sirius)
