Both Marry (Meri?) and Renko had an interested in ghosts. Actually in particular not just ghosts, but the phenomenon of unworldly interference. Something that no human would be able to explain with science or logic. Such things would only happen once, somewhere, unseen or hidden. If anyone would get a picture or a recording of such occurrence, a valuable evidence would be produced. That's what both girls agreed upon, forming the Ghost Sealing Club (Unofficial name).

The two of them had their own reason for this strange hobby. Marry strongly believed in their existence, based on her previous encounters with spirits via her dreams. She wanted to convince her friend that there were actually real. Renko did not disapprove her, however said that without any physical evidence, it's nothing more than just a claim or her friend's imagination. Thus, Marry strange dreams had no scientific value. What Renko wanted was pictures or a video, not just the stories. Both girls, each eager to convince the other one, would frequently converse about places were ghosts appeared or gossips about their paranormal activity. Strangely enough, sharing a similar interest they soon became good friends and enjoyed their free time together. A very close relation, and one that remained a secret from anyone else.

One day Renko causally invited Marry over to her house with plans to study together. They both were too lazy to do homework alone, but maybe together they would be able to do something productive, Renko thought. Marry was curious towards what kind of assignment her friend needed help with. Since they were both going to different schools, they had also different homework. Sitting down on Renko's bed, Marry inquired about the subject of the project. She gave a curious gaze at her friend, who was known of rather quite promising academic abilities. Replying casually and keeping a strange smile on her face, Renko picked up a piece of paper from her desk, showing it to Marry who read it out loud. Her surprise was that it didn't sound like something her friend couldn't handle alone. Puzzled, she glared at Renko, and then back around the room. Marry stood up and picked up the first thing her hands met, a globe that leisurely rested on Renko's desk. Because the assignment was about writing a history of an item, she thought that it was a sufficient inspiration for the paper. However, that was not as easy as she envisioned. Renko, who refused accepting the suggestion, had a different plan in mind. She wanted an excuse to go out with Marry, go out ghost hunting that is. The scheme, that sparked her friend's confusion at first, soon changed her emotion to anger. Being still agitated at Renko since the last club expedition, she declined the proposition without giving a reason to. That time, they got grounded for 2 months after they went back home the next day found by a passer-by, all soaked and with a slight cold. Renko probably forgot about the damage, but Marry was still having the shivers from just mentioning about that horrible "nightmare".

Both sat down next to each other. Renko tried making an eye contact with Marry, confronting her. She apologized for lack of empathy towards her friend and promised more compassion in the future. Marry accepted, but still kept at putting the blame on Renko. Dropping the tension, both girls eventually came back together to terms. However that didn't satisfy Renko in full, since she wanted still to go out together. With the change with her friend's mood, she hastily composed a plan. Instead of herself, Marry would be the one to choose where to go. That way she wouldn't be accounted for anything strange happening, weighting the responsibility onto her gullible friend instead. It was truly a cunning plan that she pondered. Accepting the terms, Marry did not notice the trap at first. In her recent dream she was at a vast planes of greenery filled with tall trees and colourful foliage on the ground. Nodding, Renko proposed a nearby forest that both were familiar with. However, Marry had in mind something less overwhelming, like park for example. The two of them argued about their different ideas of a place with wild vegetation. Because Marry didn't know about any parks in vicinity, she had to forfeit to Renko's mischief, as planned. She wasn't happy about that, a little embarrassed that she lost so easily and fallen for her trick. Still, Marry agreed on her friend's terms. It was because she wanted to look after her, especially because of Renko's tendency to do spontaneous stupid things.
