Actually, Kiva do not break the forth wall, it is a kind of First-person Filming, see. Breaking the forth wall meaning there is a main event in the frictional world (third dimension), but someone is suddenly communicating with the reader (forth dimension). But in Kiva, the boy (audience) is always a part of the story (third dimension).

The "no such attempts" cannot be confirmed. For example, the flashback scenes shows part of the continuity, you can find out at least the story happens to that point (judging from Forms and Kaiji in flashback). And there is also Although not obvious, but attempts are made to let HBD to fit in the timeline.
