He wishes for all of the Nightopians to be safe and at peace with one another.
NiGHTS: Journey of Dreams
"In the city of Bellbridge, a town with a giant clock tower lives 12-year old Will, a boy who loves soccer. Ever since he was little, Will has played and practiced soccer with his beloved father and has even managed to become the star player on the local soccer team. He also does well in school and served as a great role model, but it was perhaps because of his talent that he began to grow more distant with his fellow teammates.
Even still, Will at least had his father, whom he loved, trusted, and admired. Every day after work, Will's father would come home and practice soccer with his son, and the two grew quite close indeed.
One day, however, Will's father was suddenly transferred, leaving his son behind. Outside of school, Will and his father had gone everywhere and done everything together, and now, without his father, Will was plunged into unbearable loneliness. Night after night, he started to have terrifying nightmares. One night, however, a warm light appeared in his dreams, banishing his nightmares- this was the light of Nightopia, which beckoned Will to follow it, where he then had his first encounter with the mysterious being called NiGHTS."
— Will's description
Will is one of the game's two main visitors and he is avaliable from the start. The player can select his story and play it before Helen's; Will's levels are considered to be easier than Helen's and it's recommended for newcomers to chose his first to gain experience.
Will's story starts out with him playing soccer (football) with his friends (a brief cameo at the beginning shows a boy with spiked blue hair, much like Elliot), weaving the ball in and out of a row of cones. He kicks and scores a goal. He cheers when it shows a man picking up the ball coming out of the net: Will's dad. He smiles and tosses the ball back.
The next scene, Will's Dad is leaving the home. He pats Will's head, and suddenly they're outside. His dad gets in the car, which changes into a plane and flies away, Will calling for him. Will turns around to see his dad's plane flying away. The landscape turns cold and blue, and Will is surrounded by his teammates. Their eyes turn red and they start laughing, before turning into monsters. Will runs away as they chase him, then sees a bright light ahead. He spreads out his arms, and enters Nightopia.
Pure Valley is based on Will's childhood times with his father (such as how all the dandelions are like a field his father used to take him to play all day). Pure Valley is where Will's White Ideya is hidden. The boss for this dream is Donbalon.
Lost Park is like Will lost in his sadness. But excitement remains, showing his happier memories shine through too. It is also based off of how Will would be left alone with his father, or on a journey without him. In this World, he remembers how his dad took him to the amusement park every year until he went away on a business trip. Lost Park is where Will's Blue Ideya, Intelligence, is hidden. The boss for this dream is Chamelan, a chameleon that is a sort of Voo-doo Nightmaren.
Delight City is Will's dreams of what being an adult is like, which seems like a neon place full of excitement. It is also based off of Will's fun-loving side which he developed from his father. Delight City is where Will's Green Ideya, or Growth, is hidden. The boss for this dream is Cerberus, the well-known Hound of Hell.
This section requires expansion.
Will wakes up in his bed crying. After sitting up, he thanks NiGHTS aloud, showing that he still remembers him despite awaking from Nightopia. His hand balls into a fist as it glows of red light. Realizing he was sleeping with his soccer ball, he remembers he has a soccer game. The scene changes to a large stadium filled with people cheering. The monitor shows the scores between the two teams, showing that it is so far a tie. The scene switches to Will running on the field without his undershirt and vest and with red knee-high socks and black soccer shoes. A team member passes the ball to him, and once Will catches it with his feet, he sees two members of the other team in front of him. Will notices that his other team members are blocked by the other team, and his eyes close.
The scene switches to Will in his soccer uniform at a cliff with his soccer ball, his hands glowing red. Light hits him, and the scene returns to the real world. Will becomes alerted to see his father in a business suit cheering for him. Will nods his head, and runs through the other team, kicking the ball in the same way he did in the intro. When he is kicking the ball through, in a turning position it changes to him in his normal outfit turning and flying in Bellbridge, flying towards the moon. The scene lights back to him kicking the ball into the goal. People cheer while his father gives him a well-done pose. Will does a pose of satisfaction of the win, and his friends jump all over him in hugs. The scene shines up to the sun.

- Both Will and Helen used to spend a lot of time with their respective parents. However, while in Helen story, it's Helen who leaves her mother, in Will story it's his father who leaves him.
- Will, like Elliot, Claris and Helen, was considered to make an appearance as a racer in Sonic & All Star Racing Transformed, where he'd drive NiGHTS shapeshifted as the car.
