Sekiro's story is quite solemn, but it still has place for quirky characters and moments of levity.
- The sen purses' descriptions imply that Sekiro isn't so much The Stoic that he doesn't feel satisfaction having a lot of money secured in his pockets. As stated in the Bulging Coin Purse:
A purse almost overflowing with sen. It can be used to acquire the sen inside. Hefty enough to bring something resembling a grin to a Wolf's face.
- The lore description for the Pacifying Agent item foreshadows the existence of the Headless and their most infamous attack. At the same time, it really highlights the idiosyncrasies that can only be found in Japan's particular brand of superstitions:
...All who keep death close keep this powder closer, adhering to simple rule: If seized with fear, cover your rear.
- Mibu Village is overall a dreadful place, hidden in a dark valley and whose inhabitants have been turned into monsters. However, there is one NPC who gives us a funny moment as he desperately tries to pretend to be a basket and avoid notice from the other villagers. And by "pretend", we mean hiding his head under a basket and repeating the following like a protective spell:
- If you give Dragonspring sake to Isshin, you'll learn that 90% of the cast are in fact heavy drinkers who'd flock to him just to have his precious sake. Even Owl, who at this point of the story is mostly a solemn mentor figure, would come and try to get some sake even though he'd become red after the first cup.
- Progressing through the Divine Child's storyline reveals that Wolf is unfamiliar with the idea of cooking food, and has been eating rice raw all this time.
- The Fistful of Ash item is, well, a fistful of ash you throw at an enemy to distract them. Fairly useful in some situations, but it gets immensely funny once you start drawing comparisons to Dale throwing pocket sand.
- A recurring enemy is giant roosters. Yes, giant roosters. Giant roosters that players can stealth kill.
- As much of a Wake-Up Call Boss as the Chained Ogre can be, getting hurled off a cliff after it grabs you can be pretty funny.
- At the top of Ashina Castle, a nightjar ninja launches himself from a kite at Sekiro, while screaming "WOOOOOOO!" at the top of his lungs. Fans have dubbed him "The Woo Guy" for just how sudden and out of place it is, as well as being absolutely hilarious.
- The Say My Name death cry of the Armored Knight once players manage to push him off the edge of the boss arena: "ROBERRRRRRRRRT!" Doubles with Black Comedy when the Knight hits the ground off-screen with a resounding "thud", so much that even the screen shakes, as if it was a Looney Tunes segment.
- On the topic of the Armored Warrior, a YouTube commentator came to an... interesting revelation about him.
Huge, slow, slashes that hit like four trucks.
... What rings u got bithc
- Similarly to the Armored Knight are the Nightjar Shinobi on the rooftops of Ashina Castle. There's a few who are strapped to kites, and upon seeing you will detach from the kite and divebomb you while giving a hilarious yell. It's every bit as absurd as it sounds.
- The Guardian Ape is a savage fighter with the aggression and power you'd expect from a giant gorilla beast. It also poisons you by releasing massive farts (complete with wet fart sound effect) and pulls giant turd balls from its behind to be thrown at the player. It's quite a sight.
- A minor one in the Great Shinobi Owl boss-fight, sure to offer some relief in the overly tense boss-fight. Particularly as it's spoken in the middle of a fight to the death.
- At certain points after reuniting with Lord Kuro, Wolf can find him gently snoozing. Choosing to "let him be" will result in more snoozing... then more snoozing... then more snoozing. This goes on for an unreasonably long time before Kuro wakes up, complaining that you could have just woken him up. Wolf's response: "No, I could not."
- You can give Isshin some Unrefined Sake (the same thing he gives you the first time you formally meet) and he calls you out on this. Then he happily accepts and swigs it down.
- In fact, you can give him back the exact bottle of sake he gave to you as a gift. He finds this hilarious and compliments the brazen nature of your "gift", then cheerfully chugs it.
- On one occasion of sharing a drink with Emma, she will teasingly complain about a patient who was so much The Stoic that it hindered her from helping him properly. When Sekiro doesn't react, she makes it clear who she's talking about by asking if any of it sounds familiar. He doesn't get it.
- The giant Shimenawa man who carries Wolf from the Mibu Village wedding cave to Fountainhead Palace is so absurd as to be hilarious on its own. But how it gets him to the palace is even more ridiculous: it lowers a rope end over Wolf, stops, then drops the rope end and crushes him. Then it pulls itself back up, takes a few looong strides, and then proceeds to fall over against the cliff, stiff and very dead. The only thing missing is Wolf, rather than calmly extricating himself from the rope hand like he does in the game, fighting his way out of the straw rope's strands that he's been stuck in.
- Enfeeblement is not a fun status effect to get caught in, since it reduces the normally lightning-quick Sekiro into a fragile, hobbling old man who can barely lift his sword. However, it might be worth it to face the camera while Enfeebled - Sekiro looks ridiculous as a geezer, and trying to use items or the Shinobi Prosthetic will only have him look up with a quizzical tilt of his head while going, "Duh?"
- The fight against the Old Dragons of the Tree basically boils down to a bunch of old men coughing up phlegm as Wolf desperately tries to avoid the germs. As the fight progresses, so many of the Old Dragons start to spawn that the ever-growing ca-cough-phony drowns out everything else.
- The fact that most breakable objects can be destroyed simply by having Sekiro sprint through them. This reaches its peak in Ashina Castle where most of the internal walls are made of paper. Sekiro can utterly destroy the delicate Sengoku decorations by taking a lap around the palace without even slowing down as he bulldozes through them, and can even burst through walls to ambush enemies like a murderous Kool-Aid Man.
- The description for Sen Throw in the Prosthetic upgrade tree:
The dirt poor throw dust, The poor throw a little money, The rich throw a lot of money, and the filthy rich throw enough money to make all of the rest cry.
- After the Sculptor heals from the dragonrot, Emma gives sake to Sekiro. If you try to give her the exact same sake, she expresses disbelief at your actions and forces you to give it to the Sculptor instead, rather than sharing Isshin Ashina's amusement.
- With the game being on PC comes mods, and with them Carl Johnson : Grove Streets die twice.
- If you forgot to turn off shortcut key for Sticky Keys in Windows platform (press Shift five times repeatedly), expect to be thrown out of game interface in the middle of combat to Desktop screen with a dialog asking you about Sticky Key (especially when you are trying to use Mikiri counter which requires you to press Shift to dash into enemy thrust attack), as seen in this video.
