Kirishima uses this stuffed toy as her "temporary" body after her Mental Model/human avatar is disintegrated in the process of her and Haruna losing to Blue Steel, leaving only her Union Core, which Haruna places in Yotarou.
As a good rule of thumb, this tag can be used alone if Yotarou is shown as an ordinary lifeless teddy bear. However, if Yotarou shows some sort of expression, movement, dialogue, or pose unusual for a teddy bear (even just standing on its legs), add Kirishima's tag, too (since she is providing the bear's animation).
Of course, both Kirishima and Yotarou's tags can also be used together if both the two appear together in a single scene or if Kirishima emerges from some sort of "Yotarou costume."
This tag can also be used on bear animalizations of other Arpeggio characters.
