Is KOTAMON officially connected to Hololive?

No official collaboration is documented in the sources checked for this guide. The cards are best described as parody references or homages.

Does every similar-looking card count as a reference?

No. A reliable identification should have multiple matching cues, such as a specific name joke plus costume, weapon, pose, or theme.

KOTAMON VTuber References and Easter Eggs

A cautious, evidence-labeled index of the KOTAMON parody cards and VTuber references players have identified in official footage and the retail game.

Section 01

What counts as a reference

KOTAMON uses parody names, costumes, poses, and character motifs across its collectible cards. A resemblance is not automatically an official collaboration. This guide records references only when the in-game name and visual cues are specific enough to discuss and labels community identifications as interpretations rather than licensed canon.

Section 02

The oMORI card

Hololive fans identified a card named oMORI as a Mori Calliope reference. The name emphasizes MORI, and the character uses a scythe-associated look similar to the visual shorthand fans recognize. This is a parody homage in KOTAMON, not an official Mori Calliope trading card.

Section 03

The Ina-style reference

The same discussion points to a tentacle-themed character shown in the Steam trailer as an Ina-inspired joke. Because the art is suggestive and the developer has not published an official reference list, it is more accurate to call this a community identification than a confirmed licensed character appearance.

Section 04

Why the trailer matters

Several references are visible in the official Steam trailer before a player owns every card. Trailer timestamps and clear in-game screenshots are stronger evidence than memory alone, but they still establish visual resemblance rather than a formal partnership unless the developer says otherwise.

Section 05

How to report another reference

Send the card name, a screenshot or official trailer timestamp, the character you believe it references, and the specific matching cues. Reports based only on a broad archetype such as 'girl with a scythe' will remain unconfirmed until the name, costume, or another detail provides stronger support.

Section 06

Content warning for reference hunters

Some reference cards use sexualized or suggestive art. Steam applies Sexual Content and Hentai user tags to the game. Players who want to avoid that material should review the official trailer and store screenshots rather than assuming every collectible card is family-friendly.
