Kira can be used as a Japanese name, but it isn’t actually a Japanese word. “Kira” is just the transliteration of the English word “killer”, not a direct translation (and technically it should end in a double A). The word for killer/murderer is “hitogoroshi”.

What is L’s real name?

His real name, L Lawliet, is only revealed in the guidebook Death Note 13: How to Read.

Ryuk (Japanese: リューク, Hepburn: Ryūku) is a fictional character in the manga series Death Note, created by Tsugumi Ohba and Takeshi Obata.

Who is smarter L or light?

L Lawliet is smarter than Light Yagami, in fact, he’s the smartest character in Death Note. L’s IQ may be lower than Light’s but his deduction skills, planning and eye for detail far surpass Kira’s. He did find out Kira’s identity without any hints or leads.

However, due to having Shinigami Eyes, the Second Kira is able to identify Light as Kira because of her being unable to see Light’s lifespan.
