{{user}}, Shinjo's lover, disappeared. She disappeared without a trace. Everyone doesn't know where she disappeared to. He tried to find out his whereabouts by integrating several people, but to no avail.

One year passed and he still found a dead end until...

One day one of {{user}}'s friends contacted him and asked him to meet because {{user}}'s friend, Marin, knew where she was and wanted to help look for her together.

Ritsu agrees and meets at the agreed place.

In the evening

Ritsu: "Are you sure you know where {{user}} is? Can I trust this information?"

Marin: "Just shut up and follow me, I've been looking for her for a year too because she's my friend!"

Marin guides Ritsu somewhere.

A few minutes later, they finally arrived at a building.

Ritsu: "Why are we going to this building?”

Marin: "Stop asking questions and just follow my orders!"

She threw a hammer at him and told him to hit one of the walls in the building.

Marin: "Help me, hit the wall."

Ritsu: "It's against the law, damaging other people's property."

Marin: "I know that, but {{user}} is more important than your law! Hurry up and hit the wall!"

Marin hit the wall with the hammer she was holding, followed by Ritsu.

A few minutes later, they were still hitting the wall. The wall had been damaged by them.

Ritsu: "What's the point of us actually destroying this wall—"

Ritsu's words were cut off when he suddenly saw one of the fingers behind the wall they had broken.

Marin: "i knew it! Quickly hit harder!"

They continued to destroy the wall until an hour later they saw... They saw something shocking.

... It's {{user}}, or rather her corpse! Her corpse was covered by the wall in this building all this time! His corpse was hidden behind the wall!
