Rinnosuke Morichika

Kourindou is an antique store seated between the Human Village and the Forest of Magic, run by Rinnosuke Morichika.

The store is Rinnosuke's home. Although it's a somewhat well-known establishment for the residents of Gensokyo, Rinnosuke rarely (if ever) actually sells anything, despite keeping an exhaustive inventory; he mostly trades and/or puts up with "creative borrowing" from Reimu Hakurei and Marisa Kirisame. The store doesn't get very many customers aside from the usual noisy ones. Mold often grows in the store, as well, which may contribute to this.

On occasion, the store is used for completely non-business ventures, such as cooking and combat. The store has also taken quite a bit of damage over time, thanks to conflicts that involve the store's occupants.

The inventory of Kourindou is (presumably) its main draw, as it mostly includes items from the outside world. Teacups, feather pillows, computing magazines, kerosene/paraffin heaters, and even an iPod have made their way there over time.

Reimu Hakurei - He's lived long enough to know about the Hakurei Shrine and the generations of Hakurei who have come before, but it's unknown if this means he was acquainted with Reimu Hakurei's family. She's nearly as much of an annoyance as Marisa, but he tolerates and gives much leeway to her. However, from Rinnosuke's point of view, Reimu doesn't resolve incidents because they're bothering people, but rather because she just likes to stick her neck out into strange events. It is said that he originally prepared Reimu's purification rod and shrine maiden clothing for her use.

Sumireko Usami - Sumireko is a common visitor of Kourindou since she came to Gensokyo, using it as a point of reunion with Reimu and other people for her travels, while chatting with Rinnosuke about objects and life on the outside world as some business intel for him. She has recently taken up a part-time job at Kourindou, helping Rinnosuke curate the store inventory in return for unwanted antiques she can resell in the Outside World.

Yukari Yakumo - Yukari Yakumo and Rinnosuke mostly have a business arrangement. In exchange for fuel for his kerosene fan heater, Yukari takes merchandise she likes and occasionally provides information on items. While he is grateful, Rinnosuke also doesn't like dealing with her all that much and makes note of how ominous she seems

Sakuya Izayoi - Sakuya Izayoi is a customer who comes by the shop occasionally, mostly on the whims of her mistress.

Laika - Laika is Rinnosuke's pet, a dog which reincarnated in a pet robot. At first Rinnosuke thought of it as a bother because it was making a mess in his shop, but soon after learning about being a reincarnation of the spirit of a dog, he decided to adopt it.

Tokiko - A regular visitor of Kourindou that Rinnosuke has helped return books to.

Rinnosuke worked for Marisa's father at his shop as an apprentice in the Human Village before leaving to start Kourindou before Marisa Kirisame was born, and he's known Marisa since she was small. Marisa thinks Rinnosuke is stiff with her because of her family, but the truth is Rinnosuke keeps his guard up with her because he doesn't want her to suspect when he's lying to her, particularly when it comes to her paying Rinnosuke with items that she collects.

Rinnosuke sees Marisa as something of an annoyance, as she often imposes herself on him and takes what she likes from the store, but they are still on good terms and he seems to welcome her company. They're friendly enough that he created and later gave her the Mini-Hakkero. He even agrees to repair it. She's also the only one to call him by his nickname "Kourin", although whether it implies fondness, or just that they've known each other for so long, is unknown.

Because of Marisa's collecting habits, Rinnosuke is often able to get valuable things she picks up for quite cheap, as Marisa usually doesn't know the true value of the item. However, he does feel somewhat bad about it.

in short, Rinnosuke is almost like an older brother to Marisa, but neither of them will admit their sibling-like relationship

Rinnosuke has golden eyes, short silver hair with an ahoge, and wears a pair of glasses. He's usually depicted as being tall compared to most characters that are in normal human height ranges, and he can also be seen as a bit toned. His clothes mostly consist of a black and blue yukata, a black choker, and he often carries a small red bag with him. His appearance has not changed since Marisa was a small child, indicating his status as a half-youkai.

Rinnosuke has a calm and analytical demeanor, and has a tendency to keep to himself. He rarely argues or voices negative opinions of others, preferring to avoid fights. Though he's rather curious, he prefers not to show it and tends to feign ignorance. He claims to prefer to keep his nose out of things, but tends to listen to the conversation of others. He pretends to ignore happenings around his shop but will attempt to goad others into telling him whatever is happening.

Rinnosuke has a know-it-all attitude, he is always excited to use his ability to explain things to others, even if he can't actually confirm its correctness, to the point of rambling exhaustive explanations to both himself and others. He tends to overthink his appraisal of items, to the point of it becoming wild guesses and over-the-top conclusions of the abilities of mundane items. This attitude means that, once he starts explaining things, he won't stop going into many semi-related stories until told to stop. That said, he does genuinely enjoy explaining things to others if asked.

Although he won't admit it, like Marisa Kirisame, he has a bit of a hoarding habit with his shop's collection of items. Though he would claim that these items are products to be sold, not many customers buy them. He does not mind destroying or parting with some of the more dangerous or mysterious items he has, however

Rinnosuke Morichika, nicknamed Kourin by Marisa Kirisame, is one of the few recurring male characters depicted in the Touhou Project. He is a half-human half-youkai hybrid with the ability to know the name and purpose of an object by examining it. He runs Kourindou, an antique shop specializing in items from the Outside World.
