Well that okay anime, but I'm sure someone who play the game will get more clarity than one who not. From what i get we got some Yokai Monster that terrorize neighborhood, so hero called Makendo to save the day (You know normal Superhero stuff). Mai who a Makendo is just doing her duty so it's not bother her school life and not long her little sister Hikari is want to become Makendo because how cool it is, Meanwhile on the other plot Eizan that force to become Cyborg wants revenge to Dr. Mad for all that operation. So long story short those three fight Subordinate of Dr. Mad and after many 'attempts' their win by some 'explosion on robot' (tbh their not cleary state why their explode). But ofc the Dr, Mad is escape again. But at least their save the day and make some dinner that night. Not bad of OVA but lack of deepening story to make it enjoyable. For me is okay, to watch but for others prob just a skip. But Hey if you want to your watch list, is not bad to watch as other OVA that i presume you already watched.
