Personality
He is calm, innocent, patient, and usually quiet around strangers, but is cheerful and sociable around his friends. Mochizuki is good friends with Naoya Teshigawara and becomes Sakakibara's first friend from Yomiyama North Middle School. Also, Mochizuki was on good terms with Ikuo Takabayashi before he died.

Appearance
In the anime, he has a dull, light reddish brown hair and gray eyes, and wears long trousers and a blazer-less shirt for his uniform.

In the manga, he has light blonde colored hair and black eyes. Yuuya also had a more feminine look.

Plot
As Naoya's best friend, Yuuya was one of the students who welcomed Koichi on his first day of class. An extremely friendly boy, Yuuya, along with Tomohiko and Naoya, showed Kouichi around the school at lunch. On the other hand, he was unwilling to explain the curse to Kouichi.

In "Build Limbs" Mochizuki and Takabayashi are invited by Kouichi to walk home with him. The trio stopped beside the river, where Ikuo told Kouichi about the curse. Unfortunately, before he could do so, he had a fatal heartattack. Yuuya was unable to save his friend. A few days later Yuuya was one of the students who attended the big countermeasures meeting wherein Izumi decreed the class would from now on ignore both Mei and Kouichi. Yuuya was unable to keep to the class rules however, and feeling guilty, left a letter underneath Kouichi's desk, stating Kouichi should talk to Mei, as she'd be able to explain the rest.

In "Sphere Joint", Mochizuki participates in the meeting at the Inoya Cafe (which his family owned and at which his half-sister worked) organized by Teshigawara, along with Akazawa and Sakakibara.



In "Hair Stand" Yuuya was going along with Reiko, Kouichi, Teshigawara and Akazawa to the hotel where Matsunaga works and lives. Unable to meet him, however, the kids decided to wait at the beach and spend the day relaxing, assuming they were safe from the curse. Yuuya was buried in the sand by Izumi and Kouichi, while Takako tickled his feet to keep him from resisting. Teshigawara decided to have a "contest" ; fishing for lunch ingredients. Mochizuki was in the team Non-existent with Mei and Kouichi, much to his irritation. Though he had a fun day with his friends at the beach, a pall was cast on things when Junta started to drown while trying to recover Takako's beach ball. Yuuya was the only boy who remained on the beach, as Naoya, Kouichi, and Matsunaga rushed to help him. They were, unfortunately, too late, and Junta was hit by a speed boat and eviscerated, much to the group's horror.



In "Body Paint" Mochizuki meets up with Kouichi and Teshigawara to look for the item that Matsunaga left in the old classroom. They found a recording tape and unfortunately Teshigawara broke the tape later on. Yuuya offers to repair the tape himself.

In "Glass Eye" Mochizuki repaired the tape, and had heard the most important part along with Mei, Teshigawara, and Kouichi. Also, he took Mei's side when Izumi confronted her about the deaths.



In "Makeup", after knowing that there was a killer around, Mochizuki suggested to look for Ms. Mikami first. He and Teshigawara went around to check and when they reached a room. They found Keiko in the room with blood stained chopper, Keito attempts to attack them and during the process, the chopper cut Teshigawara's leg. Mochizuki went to help Teshigawara escape from Keiko but Keiko followed them along the hallway. Also, Yuuya showed the tape to Takako and Izumi. After a fire broke out at the inn, Kouichi detailed he and Naoya to warn their classmates of the danger. Unfortunately, when trying to find Mikami-sensei, they instead encountered a deranged Keiko Numata, who'd already nearly killed Takako and Manabu Maejima. The two were forced to abandon their mission as she began to pursue them through the burning inn.



In "Stand By Oneself", Yuuya pushed Teshigawara out of a window while running from Keiko. He was about to jump out as well when Keiko grabbed him and started pulling him back up towards her. Teshigawara jumped up and pulled back, sending Keiko and Yuuya crashing to the ground. Keiko attempts to kill Teshigawara but they're saved by Chibiki. Chibiki leads them to his car where he tends to Teshigawara's wound.

The anime ends with Yuuya and Teshigawara putting a tape they recorded about how to stop the calamity into the locker where they found Matsunaga's original one.

Kouichi Sakakibara
The two became friends quickly. They talked about art among other things. He was present when Takabayashi died; before he died Kouichi asked him for the class roster - after ignoring Kouichi he slips a copy into his bag and asks for forgiveness as he did not want to pretend that Kouichi did not exist. They were able to make amends and stayed friends.

Mei Misaki
They had a little interaction through the manga and anime. The two were paired, along with Kouichi, by Naoya for the catching contest. The two didn't interact much, but were on friendly terms. In episode 10, Yuuya defended her from Izumi.

Naoya Teshigawara
They are best friends and usually do things together. Throughout the Anime and Manga they are usually together. When Keiko went insane and wounded Naoya, Yuuya aided and saved him; and in return Naoya saved him as Keiko tried to attack him; she was later killed by Chibiki. After the Calamity had ended they both created a tape and thoroughly explained what to do; they put the new tape into a locker where they found Matsunaga's original one.

Reiko Mikami
Yuuya had a crush on Mikami-sensei. He spent time with Reiko when they went to the beach together (Episode 8) and was exstatic to ride in the Mikamis' car next to her. Later he and Naoya went looking for her, though instead they only encountered Keiko Numata, who immediately began trying to kill them. In the manga it is made much more clear that he has a crush on her, as he visited Kouichi's house specifically to check on her at one point to make sure she was okay.

Tomohiko Kazami
Tomohiko and Yuuya are friendly, though not especially close in the anime. In the manga, where Tomohiko is a much more major character, the two are together more often, and Tomohiko's sisters have a crush on Yuuya. At the end of the manga, Yuuya and Tomohiko were together with Naoya at the hospital when he went to see Izumi, suggesting the three's friendship remained strong following the catastrophe.

Takako Sugiura
The two don't interact much, though Yuuya seems to be one of the few people Takako doesn't find extremely irritating. Yuuya and Naoya threw her in the ocean in "Hair Stand" and later on, when the group buried Yuuya in the sand, Takako tickled his feet to make sure he didn't try to escape, suggesting at least some degree of familiarity. However, the two didn't interact again outside that episode, as Takako spiraled into depression following Junta's death, and Yuuya focused on his friends' efforts to break the curse. However, when Yuuya tried to bring the girls up to speed on his friends' progress by playing them Matsunaga's tape, he inadvertently planted the seeds of Takako's psychotic break down, leading to her death.
