In The Boy Who Fell
While she has not physically appeared in the comic, Hilde has been mentioned by Ren several times.

In Chapter 01 - Hell Kitchen, Ren apologizes to his mother as he falls, presumably to his death, that he will "be able to see Dad again before [she does]".

In Chapter 11 - Dark, the thought of Hilde enables Ren to overcome his fear in the battle against Hond.

In Chapter 19 - Reunion, Lord Devil conjures an illusion of Hilde to cheer Ren on.
