Yusuke's Species
If Yusuke Urameshi's forefather was a demon, and a human from the start, does that make half-human, half-demon, right? Like, Kurama?
Minoru Kamiya's Territory
Their was something on my mind on Minoru Kamiya's territory. The power Mad Doctor, is it the name for his battle style or his territory? Because I'm curious about the name of his territory's name. If anyone has answers, please leave comments about his territory.
The Tougro's Intimidation
It seems the Toguro Brothers spirit energy is so powerful, anyone looking at them or sensing them will be terrified. Yusuke was intimidated on how Younger Toguro's power is, the fact he survived Kuwabara's spirit sword (the fact he took the hit) and every time those two make eye contact, Yusuke shakes out of fear. Kuwabara was in shock on how he's still alive and saw he bring down a construction building. Even Hiei was nervous when he senses the brothers spirit energy in Ganzo's house where his sister Yukina was held prisoner.
Age
If the characters birth are shown, then what year are they born on?
Example:Kaname Hagiri and Minoru Kamiya.
Kaname's Sister
In the episode "Topside", we seen Kaname alongside his sister. What is his sister's name and what are her powers? The least the directors and editors can do is to give her a name so they don't leave us, the "audience", to wonder.
