Sometimes, it’s less “Haachama-chama!” and more “Haachama-chamaaaaAAAAAAAAHHHH“.
- As a part of her Horror Contest in August 2020, Haachama uploaded a compilation video featuring some of the best submissions. They’re... unsettling to say the least. Content of said video includes:
- A parody of a movie trailer about Haachama being a demonic entity who intends to brainwash any viewers who see it, even from a monitor, into becoming insane. This culminates in a chase scene where a giant distorted Haachama chases a Haaton on all fours, and a Bolivian Army Cliffhanger where her INSANE CRAZY CONTENT song is further Played for Horror.
- A very short bizarre video some jokingly described as a witch's labyrinth.
- What you get when you combine the already creepy Japanese children's game song Kagome Kagome with Haachama and make it a straight up horror scene.
- A horror short depicting what might be Akai Haato's last moments. Is also a Continuity Nod to an earlier video Haachama herself uploaded onto her channel titled "正気な狂気".
- Emm... whatever this is (volume warning).
- A parody of a segment typically seen in Japanese paranormal sightings television programs.
- In February 2021, Haato went full in on creating lore regarding her Split Personality between Haato and Haachama over the course of several videos and streams, resulting in some of the most creepy and horrifying moments in all of Hololive.
- As a part of the conflict between Haato and Haachama, there's this incredibly disturbing moment where Haachama decapitates Haato on stream. Yes, you read that right. A couple of frames even straight-up shows the hololive idol being headless, albeit without blood.
- Two streams after, the decapitated head of Haato is directly shown on-screen, held by presumably a headless body.
- Soon after, Haato stitches her decapitated head onto Haachama's body, sporting stitches on her neck just like her Haatons.
- Haato herself has also become In-Universe Nightmare Fuel for the other girls, with Subaru, Flare and Polka fearing her, being unsure how to call her and being afraid to even get close to her in games such as Minecraft.
- At first, the fan game Haachama Cooking Simulator is just a simple point-and-click game making fun of her propensity to cook and eat just about anything. Then Haato pulls out a tarantula from the fridge and the game starts ominously glitching out... shortly followed by a scene that wouldn't be out of the place in a ".exe" Creepypasta.
- On February 16th, Haato streamed an unarchived singing session... paying no attention to Haachama's still-breathing head at her side, with a pitch-black background of nothingness behind her.
- Her final stream of February involves showcasing the submissions of her Horror contest, and that includes a fanmade platformer. Everything looks fine at first, aside from the occasional scream on death. But on the way to completing the second level, she encounters an ominous-looking doorway that causes the game to glitch out. Suddenly, innocuous setpieces on the subsequent levels turn lethal, killing her on contact while transforming into a more grotesque form. Haachama then starts contacting her, lending her her Haachama Vision to help her, peeling away the world's cutesy facade to reveal its nightmarish nature. The world then degrades into Platform Hell culminating in a nightmarish Final Boss that leaves Haato sobbing in frustration and fear. It is arguably the most disturbing stream she has done yet where you cannot tell if the screams are coming from the game or Haato herself.
- In September 2021, Haachama uploaded a video that is her own rendition of "☆V☆E☆A☆H☆". It mixes Body Horror, Creation Myth, and Mind Screw with a mesmerizingly catchy beat, perplexing (at best) the non-Japanese audience on its release. Miko's reaction to the video has her comparing it to Doki Doki Literature Club!.
- In November 2021, Haachama had what was allegedly going to be a tequila drinking stream. She already sounded a little drunk when the stream has just started, so the chat was worried for her health, especially once she shifted to "one shot for every death in Slither.io" and was dying quite frequently. About an hour in, it turned into a karaoke stream, but the fact that she seemed completely sober while singing despite sounding like she was about to pass out when speaking started to clue people in that all wasn't what it seems. At around the 2:20 mark, the ED plays, but the stream continues afterward with Haachama playing some more Slither.io. Not long after, she tries to sober up... only to end up heading in a completely different direction.
Cue over an hour of eerie music, unsettling humming and laughing in an Acid-Trip Dimension, spontaneous Word-Salad Horror like the following dialogue, "This is not reality", "Welcome to Haachama World", and "As long as everyone is conscious, this will continue forever", all while the chat follows her "PRAY TO HAACHAMA" command a la Religion of Evil. When it finally ended, she uploads a video titled "HAACHAMA DRUG", with the only thing in the description being "🙏🙏PRAY TO THE GODCHAMA🙏🙏". Essentially, drinking stream unexpectedly turns into Surreal Horror and one of the most bizarre streams to date. - In Usada Pekora's Human Rabbitality Project, Haachama was among the holomems that did a Pekora impression. When it was her turn, she gives the lightheared tone of the event a complete 180 by explaining how some pieces of her outfit were made from murdered Nousagis.
