Till 13 epsiodes they show much more of it. I don't realise when I was on 13 epsiodes. Some of the epsiodes are dam serious where as some are funny. 

OVA epsiodes are also pretty good. Characters are unique in their own. I like watching this kind of isekai anime.

It's good to see how in starting he knows his don't have strong power to he spend time studying things which help him later and he build some awesome gadgets for himself and others.

I highly recommend you to watch it.

Plot is so good. Now waiting that next season come quickly.
