Creating the non-stereotypical zombies is what makes the story unique and super-fun. It's especially more so when you chose Ohno to be a zombie leader since he is such a contradiction in RL. Someone who can be so slow and absent-minded then turn really agile and adept in the next. It is certainly a fantastic choice you did here.

Please, if you do have time and can find your inspiration, write the Juntoshi backstory. It definitely would be a Blast! I will be wishing and hoping for it :D
