 Light Yagami , the true identity of Kira , discovers the location of Mello 's hideout . An indirect result of this is that Mello meets the Shinigami Sidoh , the original owner of Mello 's Death Note . Sidoh reveals to him — in exchange for some of Mello 's chocolate — that there are two extra fake rules ( in addition to a number of real ones specified to each Death Note 's owner ) . Mello begins to theorize that whoever Kira is , he probably used these spurious rules to fool the Japanese police into thinking he is innocent . However , Light launches a SWAT team led by Soichiro to raid the hideout . In order to escape , Mello detonates remote @-@ controlled explosives , after one of his Mafia accomplices fatally wounds Soichiro . Mello is left with a scar on his face , and the failure of his Mafia scheme leaves his real name in Light 's hands .
