I am giving my opinions for the numbers I used for 2 of the side stories from the LN's as this says 'Heavy Object S' though it doesn't say if it is an LN side story or if these 3 are manga.
If this is for a manga, please include the LN side stories to be marked as well. It woudl be nice if you also fix the time scallnig for the LN's read in our profiles to not show only some 30 to 60 minutes at most like it is some manga. But to be shown as when reading the shorter ones that they can take 3 to 5 hours & longer ones like 'Tanya the Evil' can take 7 to 9 hours each. Really, only 4 days, 19 hours 45 minutes showing for over 236 LN's read???
