At last, I have been able to read it all in English, rather than just look at the pretty(?) pictures, since the last third was never translated, and the last half could no longer be had for love nor money. Admittedly vol. 12 is still only there in the form of separate script and raw, but that's one of the perks of having leapt at the chance of proofing the scripts for volumes 10-12 — the edited version probably won't be released until the end of January.
So we find that the anime had subtle spoilers for parts of the manga that hadn't yet been translated, and exactly what is going on in the bleak concluding volumes, in a way that existing synopses had failed to achieve.
At times a bit shaky, darting off in directions that never quite come to anything except to in passing reveal a fragment of what is going on; but in the last three, previously untranslated, volumes, picking up momentum to the final resolution.
The End of Narutaru.
