The doctor who treated Kaino at that time was a little suspicious because Kaino's blood wasn't red. However, a little green is exposed to poison. There was a sense of suspicion when he remembered that the IV was not transparent white, but more fluid than usual. The doctor contacted Kaino's family.
"Hello, excuse me. With the Kaino family?"
"Yes. Who is it?" asked Kaino's Mom.
"I'm Doctor Braha from the hospital that Kaino had treated. Can we meet for a moment, Ma'am? There's something I want to talk to you about."
"Is this related to Kaino's death, Doctor?" Kaino's Mom asked again.
"Yes, Ma'am. I hope you can come," answered Doctor Braha in a restless tone.
"Okay, Doctor. I'll be there. Thank you."
