The Death Note works on a short list of rules, and the story is what happens when a very clever person reads them. The human whose name is written in the notebook dies. The writer has to know the person's face. If no cause is given, it is a heart attack, forty seconds later. Every trap L sets and every trap Light sets for L is built from the corners of that rulebook.
Here is how the notebook works, who Ryuk is and why he dropped it, how the contest between L and Light is structured, what Misa gives up for the shinigami eyes, and why an apple keeps turning up. Where our own Death Note collection depicts one of these, it is linked in place.
The rules of the notebook
The rules are written inside the cover, and the first four do most of the work. The human whose name is written in it dies. The writer must have that person's face in mind, so people sharing a name are not affected. If a cause of death is written within forty seconds of the name, that is how it happens; if not, it is a heart attack. If a cause is written, there are a further six minutes and forty seconds to add details, and, within physical limits, the victim will carry them out.
The rules underneath those are the ones the plot runs on. Anyone who touches a notebook can see and hear the shinigami it belongs to, and no one else can. A person who gives up ownership loses every memory connected to the notebook, which is the mechanism behind the series' most audacious move. And the human who uses a Death Note can go to neither heaven nor hell, a line the story repeats until you realize it is not a threat but a description.
The book itself is the design on the Deathnote tee and the Deathnote hoodie, and the act of writing in it is on the Reaper Script tee.
Ryuk, and why he dropped it
Shinigami are gods of death who live in a barren realm of their own and extend their lives by writing human names in their notebooks, taking the years the human had left. Ryuk drops a second notebook into the human world for the plainest reason: he is bored. He is not on Light's side. He tells Light at their first meeting that when the time comes, he will be the one to write Light's name, and at the end of the series he keeps that promise.
What makes him work is that he is an honest spectator. He does not lie to Light, he does not help unless there is something in it for himself, and the rules of the notebook are the only thing he takes seriously. His face, the round eyes and the fixed grin, is the most drawn thing in the franchise. It is on the Death Grin tee and, with wings spread, the Winged Verdict tee. The Fallen Shinigami x Light two-sided tee and the matching knitted sweater put him and Light on the same garment.

L versus Light
Light Yagami finds the notebook, tests it on a criminal, and within days has decided to use it to build a world without crime, with himself as its judge. The public names the invisible killer Kira, and the police bring in L, a detective known only by a letter who has never shown his face and works through an intermediary named Watari.
The contest is a chess game played with the rules above. L's opening move, a televised broadcast, uses a stand-in to prove that Kira needs a face and a name to kill, and narrows the killer to one region of Japan from the timing of the deaths. Light's counters escalate from there: joining the investigation team, engineering situations where being suspected proves his innocence, and eventually surrendering the notebook so that he forgets everything and can pass any test. L is never fooled and never has proof, and the middle of the series has the two of them chained together at the wrist, each waiting for the other to slip.
The Shinigami's Chess tee and the Death's Chessboard tee take that structure as their subject. L is on the L Silent Justice tee, crouched the way he always sits; Light is on the Dark Genius Silent Killer tee, the Killer's Intent tee and the Death's Dominion tee.

Misa and the shinigami eyes
Misa Amane is a model whose parents were murdered in front of her, and whose killer was later executed by Kira. She has a notebook because a shinigami named Gelus broke the one rule that kills a god of death: he used his notebook to save her life, and turned to dust for it. The shinigami Rem carried his notebook to Misa, and Misa went looking for Kira to thank him.
The shinigami eyes are the trade that defines her. A notebook's owner can ask the attached shinigami for the ability to see any person's name and remaining lifespan by looking at their face. The price is half the owner's own remaining life, paid on the spot. Misa makes the deal without hesitating, loses her memories along with the notebook, and later makes it a second time, a detail the series states plainly and most readers miss. Everything she does is for a man who values her exactly as much as her eyes are useful to him, and the story does not pretend otherwise.
She carries more artwork than anyone but Ryuk: the Misa tee, the Devotion tee, the Dedication tee, the Shinigami's Embrace tee and the Goddess of the Shinigami tee.

The apple
Ryuk is addicted to apples. Human-world apples, specifically; the ones in the shinigami realm are, in his words, like sand. Deprived of them he twists himself into knots, and Light uses the craving as a leash more than once. The image stuck: a black-clad shinigami holding a red apple is on the covers, in the opening credits and on a large share of the fan artwork.
The apple works as a symbol because it does two jobs at once. It keeps a god of death compliant, and it is a very old image of temptation and forbidden knowledge in the hand of a student who has decided he is entitled to judge everyone. The series never explains it. It does not need to.
How this translates onto cloth
Death Note's visual language is already monochrome: black notebook, white pages, a grinning shinigami drawn in ink. The artwork here is mostly line work on dark cloth with a single accent color, and it reads at a distance for the same reason the original covers do.
Most pieces are vintage tees: 270gsm garment-washed cotton, pre-shrunk, in an oversized drop-shoulder cut, with a bonded matte print that sits flat against the cloth. The two-sided tee carries Ryuk on one face and Light on the other. The knitted sweater is a 100% cotton knit, pre-washed, with a ribbed crewneck, cuffs and hem, where the design is part of the knit rather than a print. Measurements for every size are on the sizing page in both inches and centimeters, and everything ships tracked with 14-day returns and size exchanges from delivery.
The full set is in the Death Note collection.
