Enjoyed Zeff and older Zeff too, they had such differing personalities just because of a couple of different interactions when Zeff was young and therefore made life so completely different for the two it was really cool to see. Granted, the ideal was to get as strong as possible, as efficiently as possible which I think was achieved due to the fact his goal was to help Millie's guild become the strongest. It's a great story about how your perspective and personality can change drastically depending on your experiences with other people, and that different futures can be real by the choices you make. Glad Grain was forgiven in the end, since his will to live and to get revenge kept him alive for so long, he because old and bitter, it was good that Zeff recognized this and helped Grain out. Overall, good story, great characters and awesome drawings. 8/10 due to the harem aspect, could have dropped that and it would have been a wonderful story.
For those wondering if yamato class was nuclear or not the answer is no but it had 9 most powerful 16inch naval gun and it was the biggest ship with most firepower ever made and when it's gun fired you can literally see the big shockwaves spreading through the ocean and that shockwave was enough to throw even most tightly gripped person out of ship so no one was allowed to be in deck but due to aircraft carrier these big "BATTLESHIP" which were considered overlords of ocean became less cost efficient and thus obsolete till today these battleship were so powerful that they could preety much one shot anything and if one got you in its sight then you should preety much surrender your ship.
