So, I am at around episode 20 of S1 of Shakugan no Shana.
The plan is to read two of the only 3 volumes TLed, in other words volume 7 and 8 and skip ahead somewhere to S2.
Then the plan is to get anime content for volume 9 and read the manga adaptation of the 10th volume (and the wiki summary for the non-TLed volumes of that).
Which episodes should I skip in S2 and which ones should I watch and what volumes do they correspond with?
