Light’s Eye Color Change
Originally in the beginning, you see lights life span through Ryuks eyes. Light had to find out when battling Mello when Shuichiro made the eye deal. Whenever Light thinks to himself while in Kira mode, his eyes glow red to give an evil context to the viewer. When he’s revealed to be Kira in the warehouse, he no longer has to hide from the group; he enters Kira mode and his eyes turn red as a result.
Light’s Capture
The answer is Never. Light Yagami knows his story and fate. He will never be caught because he isn’t going to do the mistakes which ultimately got him killed, at least he won’t give off his location, Japan, which was the biggest mistake Light made in the anime.
Ryuk’s Relationship with Light
Ryuk never actually cared about Light in any affectionate way. He thought of Light as entertainment, bored and dropped the death note on purpose so that someone would find it.
The New Kira in Death Note
The miniseries "Death Note: New Generation" and the film "Death Note: Light Up the NEW World" introduce new characters who act as Kira. After Light’s death, Ryuk brings a Death Note to Light’s son Hikari Yagami, who begins acting as the new Kira with the help of his guardian Teru Mikami.
L’s Knowledge of Light
L Knew Light Was Kira And Lied Throughout the anime, L’s suspicion of Light wavers from episode to episode. Generally, though, he says there’s about a 5% chance that Light is Kira. Di conseguenza, what is L’s religion? No, L is most likely an atheist or non-religious. He speaks about the existence of a god as one might speak of a hypothetical new species or theory in science that may exist, but as far is known does not in fact exist.
