Maybe I will give it a try and translate volume 17 characters chart (as it was slightly updated till volume 16 -- but for basics you might check it out!). And I don't really know where to start summary lol.
Summary:
Abe (little angry guy) and Watanabe (tall stoic guy) were as far not active in the story, because they had no connections to past life. But Abe's memories are abruptly awoken when they were cleaning the class as he found small round red candy - it reminded him of Veronica's earring, which they needed to get to the "safe place" during the raid on the castle. Abe acted dangerously, but in the end he calmed down. At karaoke meeting it became clear that he is the only one so far of knight's of Moswick mainland forces - and they were told that Veronica was evil so they attacked them. Abe changes his whole demeanor and engages in a duel with Nishina. The one who stops them is Yamada (in the past a priest Patty Herschel) who wasn't so active till now too. She reveals her role was "supervisor", basically saying she had her own role into whole past mess. So a duel is cancelled but they are still very confused about Abe's testimony...
Btw next chapter is gold
@Blackbird Haruko I'm afraid Haruko's role now is just to stick to Minami's side and support him.
I'm current main translator of this series for Deus ex Scans too. I buy online raws on eBookJapan and read them (and translate them later - you can find my LJ; today was released chapter 86 and it's WOHOOOOOOOOOOOOO).
@nanamka Thank you for your translation. Bokura no Kiseki is one of the series where you would have no idea what's going on if you just look at the raws. @yosua753@Shinobu@dicedmangoes@AHomicidalTelevision No need to reread the manga. You can find extremely detailed and up to date story & character guides on the Bokura no Kiseki subreddit.
@youdontknowwho Well i think reading a summary is good for someone who doesn't have time, but it's always good to reread if you want to remember all the scene thats happening in this manga.
Thanks for the sugestion.
