The written ramblings of one of two Manchester men accused of plotting to kill international music star Joss Stone have been shown to a jury.
Kevin Liverpool, 35, wrote down in a diary his thoughts about the Devon-based soul singer.
Other entries talked of the need to buy a semi-automatic gun, a gun holder, a silencer and infrared equipment, as well as a "ninja sword".
Liverpool had also written a reminder to buy a hooded top, car insurance, a safe and open a bank account, Exeter Crown Court heard.
He wrote of "war", "warlord #1" and of "missions" to "rob" and "discipline".
Liverpool and co-accused Junior Bradshaw, 32, are charged with plotting to rob and kill Miss Stone before dumping her body in a river in June 2011.
The defendants, both of St Stephen's Close, Manchester, deny charges of conspiracy to murder, conspiracy to cause GBH and conspiracy to rob.
The diary was seized by police when they raided Liverpool's one-bedroom flat in Longsight, Manchester, after he had been arrested in Devon.
In the diary - a daily appointment 2007 edition - each page was covered in handwritten scrawl, in either blue or black ink, with much of it crossed or scribbled out.
Detective Constable Katherine Joyner took the jury of 10 men and two women through the diary.
She said there were quite a few references to urban slang words, such as "wet" - meaning to repeatedly stab someone until their clothes are soaked with blood - and "popo" - short for police.
Liverpool had also written a list, numbered 1, 2 and 3, of "rob", "wet/injure" and "death".
The notes included details of Miss Stone's date and place of birth and a biography of her musical career, including the albums she has released.
Liverpool refers to Miss Stone, who gave evidence to the court on Tuesday, as "princess".
In the diary other musical stars were listed, such as British rapper Dizzee Rascal, Eminem, Beyonce, Craig David, R Kelly, Chris Brown and Girls Aloud.
The court heard that, on another page, a note Liverpool had written was entitled "Game of life".
It went on: "My way (move).
"Inj: chop off arm leg crossbow
"Kills: decapitate them."
Jurors have heard that a stash of weapons was found in the defendants' car.
A uniformed Pc discovered a black-handled samurai sword with sheath, two knives and a length of green garden-style hosepipe in the boot of a Fiat Punto being driven by Bradshaw.
On the back seat of the burgundy hatchback, police recovered a black hooded top and a black and grey rucksack.
The rucksack contained a roll of black bags, a roll of black tape, a hammer bought for #1 from a Manchester DIY store, a black and yellow spike, spark plugs, a sock and a carrier bag.
A second #1 hammer was found in the front passenger footwell of the car, along with three black gloves and a black hat.
A black balaclava was also recovered from the rear of the car as well as AA Route Planner printouts from Manchester to Devon, the court heard.
