A very good manga

I am liking where this manga is going it is really entertaining. I really like the characters all of them are interesting to read about especially Shiki, Rebecca and Happy all three are such great characters. I also like younger Weisz he is interesting and does what he wants and is selfish in many ways he is still interesting to read about. I really liked the plot the characters somehow went
back in time they meet the younger version of Professor Weisz other things happen fights happen they meet an abused robot things are solved they get to a ship and fight another character after that they have a new ship looking forward to reading more.
