Dear Otakus,
We were checking a list of “unsuccessful queries” (meaning you tried to look for them but didn’t find any hits in our website >.< ) and found that some of the titles you’re looking for are in fact, available but simply spelled or worded differently.
For instance, “Deathnote” is saved in our database as “Death Note” or “Shingeki No Kyojin” as “Attack on Titan” or “Yotsubato” as “Yotsuba To”.
You may try to look for the same title but type it in another way. Please note, too, that almost all manga are saved in their English title for now. However, we are working on saving Japanese titles equivalent to their English counterpart so that they will come out in the search results next time.
We may not have some of the other titles you’re looking for so feel free to write us here and then we’ll get to them as soon as we can.
Thank you very much for your time and patience!
– Rizza and Jo
