Obviously Hanyuu can't physically help, but she does have the ability to reassure Rika with her words- but instead, she's been rather of a pessimist thus far in the Minagoroshi anime, putting a damper on that hope which Rika does find thanks to the strength and support of Keiichi and her friends.

She is probably just trying to make things less painful for Rika if (or when) the world does end in tragedy, but at this point there's nothing to be gained from that. She could be genuinely useful by keeping Rika's spirits up and encouraging her to make the most of every world, instead of always giving up at the first sign of adversity.
