Summary
During the Fall of 2017, Takafumi learned that his Uncle who had been in coma after getting involved in a traffic accident 17 years ago has woken up, and so he goes to meet him. Upon arriving, Takafumi's Uncle starts talking to him weirdly, which prompts him to think that his Uncle is suffering mental damage, which only solidifies after his Uncle claims that he was excited to return back from the Another World "Granbahamal" after 17 years. When Uncle asks Takafumi about what the other family members were doing, he learns that the whole family is separated and even his sister didn't want to do anything with him, which prompts Uncle to write down something in a small notebook and chant "Icuras Cuora" after that. Uncle tries to prove to Takafumi that he really went to Another World, by using Magic which initially fails much to Takafumi's dismay who is trying to explain about his financial issues to him and not being able to support him, when suddenly Uncle triggers a Wind Magic while using Japanese, proving his claims. Seeing this Takafumi gets excited and forgets about his talk about not being able to support his Uncle. Uncle meanwhile asks Takafumi about the Console Wars and the situation about Sega, and gets distraught when he learns about Sega had pulled out from the Console market, so he immediately writes down on his small notebook and chant "Icuras Cuora" after that. Takafumi gets interested and asks about what "Icuras Cuora" is, and Uncle reveals to him that its the Memory Erasure Spell, which he uses whenever he experienced something unbearable, though he writes down about it in his small notebook before erasing. Takafumi gets interested and asks if he could read the notebook, which he immediately regrets after reading it and asks his Uncle to use "Icuras Cuora" on him. A week later, Uncle gets discharged and moves in to live with Takafumi in his apartment. Meanwhile Takafumi decides to monetize his Uncle's powers and started posting videos of it on YouTube, which helps generating ¥60,000 Yen in Ad Revenue.

Later on, Uncle questions Takafumi on why he got such a big room to live alone to which he replies that he was originally a Roomshare setup but because of issues it didn't work out. Uncle is surprised to here the term "Roomshare" which he never knew and thinks that Takafumi was living with a girl. Takafumi clarifies about it and is surprised to learn that Roomshare didn't exists 17 years ago (while comparing a Smartphone to an Electronic Dictionary, to Takafumi's surprise). With the talk buddies going on, Takafumi asks Uncle about his companions in the Another World, to which Uncle informs that he was mostly Solo for 17 years. Primary reason being that everyone in that Another World was really good-looking, while he was hunted down as a sub-species of Orc. Uncle talks about one particular person who followed him around regularly and harassed him, and would launch attacks and verbal abuse towards him. Takafumi is sad to hear that Another Fantasy World's aren't really that good either. Uncle continues on to say more stuff about that person, on how first time he saved her, rather than saying thanks she was pretty rude to him. As Uncle continues to talk more about the person, Takafumi comes to the realization that the girl was actually a Tsundere, and remembers that the concept of Tsundere didn't originate until 4 years after Uncle departed for his journey. Uncle laminates that things didn't go well for him in the Another World, and shifts his focus to interact with his Commenters from around the world on Internet, but is unable to keep up with the terms and things going on.

One day, Uncle shows interest on buying a Turn Model Cellphone from an Auction. Takafumi says that since it uses old 2G signal, it won't be of use under modern standards. But Uncle isn't worried as he won't be using it anyway, as there is no one to call to. While Uncle is surprised by the amount of stuff a Smartphone can do, he laments about the lack of gimmick in them. He notes the fact that 17 years has changed a lot of stuff and developed new innovations. He then mentioned about how he also once innovated an item in the other-world and shows his memory about the incident using the spell "Icuras Elran". He had crafted an "ever-brimming pot of water" using spellcards, for a village suffering from a drought. Takafumi is impressed by the news and compares it to the Overpowered Modern Science Trope, and thinks that the villagers must have sung praises and gratitude for Uncle. But in reality, the villagers had tried to hang Uncle because the shape of the item was sacrilegious, and they smashed the item. And while the villagers were trying to hang Uncle, Elf arrives in order to stop them. While Elf was trying to mediate the situation, Uncle took the chance to escape. Takafumi becomes frustrated with the situation, though Uncle misinterprets it as Takafumi doesn't like the first-person view of the incident. So Uncle turns the point-of-view in his memory and shows Takafumi who he was treated. Takafumi asks Uncle if its possible to see what happened with the Elf, to which Uncle focuses on the background and sees the Elf being a bit disappointed that Uncle had ran away and she starts fighting the villagers who attacked her. Suddenly Uncle gets an notification of the Auction on the Cellphone closing down soon and in a hurry orders, without checking the shipping cost, which turns out to be 2,000 Yen for the item, since it was being sold by someone from an isolated island. Takafumi laments that if the location was closer, then they could have picked it up personally to save the shipping cost and considered the incident as a lesson learned. Uncle suddenly jumps out of the window to Takafumi's surprise and flies away, returning back from his trip 30 minutes later with the Cellphone in hand and shows it of to Takafumi, who in-turn asks Uncle whether he could pick up similarly auctioned item, to which Uncle agrees.

Takafumi receives a package of Rice delivered by Amazon, and asks Uncle to hand him something to cut the box. Uncle hands him a short-sword which surprises him and he asks Uncle were it suddenly appeared from. Uncle then shows him his Storage Magic which withdrawing his small notebook from it. Takafumi asks if Uncle had brought more stuff from the otherworld, to which he tries to takeout a Magic Sword, and accidentally hits the wall much to Takafumi's dismay. Uncle next takes out a Ring with a Magically Crystalized Mermaid's Tear which is mounted on a Ring carved from Rainbow Coral, which is rare enough to sell for enough to allow a person to create a Castle with its money. Listening to this, Takafumi wanted to sell the Ring, but Uncle informs him that he had already tried to sell and it was priced at 50 Yen, because the materials used in the ring were so rare no one knew what it was so it was treated as a children toy. Uncle starts thinking about ways to boost his view count by using new inspiration. Takafumi asks whether Uncle wanted to give the Ring to someone as he was carrying it around, to which Uncle informs that it was a trophy item which he got after clearing a hard dungeon. Seeing Takafumi down afterwards, Uncle asks whether he wanted to talk about Love, and shares his story of his first love which were Sonic & Tails. Uncle reminiscent about visiting Toy store to admire them while viewing the Title Screen. Takafumi asks Uncle, whether he had ever fallen in love with someone, to which he gets the answer of Uncle falling in love with Kaede Nanase, a game human character. Takafumi asks if Uncle ever meet girls in the otherworld, to which Uncle agrees and shows him his Memory of saving a girl and her siblings from an Orc. While initially thankful, the girl eventually overcomes with despair upon seeing Uncle, and decides to sacrifice herself by giving herself up to Uncle to save her siblings lives. Uncle, having misinterpreted the situation, thought that the girl was happy and thankful to him, but he suddenly blanks out and thinks that some goblin might have attacked him from behind unknown to him who then threw him into the river. Takafumi notices in the Memory that the siblings of that girl were making quite suspicious moves while trying to get behind Uncle, and considers the possibility that it wasn't a goblin attack but rather the sibling attacks Uncle from behind. Later on, Uncle In order to thank the Elf, Uncle forcefully puts a ring on her finger, which he later takes out and sells for money (much to Elf's dismay). Takafumi admires the tenacity of the Elf girl.
