The Daichis are a family in danger of tearing itself apart. Dissatisfied and money obsessed mom Seiko has served wimpy and otaku dad Mamoru with divorce papers. Daughter Nozomi who has always been saddled with all the housework, feels pained that everyone is using her. The youngest albeit most foul mouthed, Dai is forced to watch all this as everything is going to pieces. However when the Galaxy Federation recruits the Daichis to combat alien threats to the wellbeing of the Earth, it will be a chance for the family to save the world and maybe themselves.

If you’ve looked through Shouji Kawamori’s massive backlog before, then you’d be aware of the occasional original concept that takes a departure from his iconic mecha anime. For myself, learning about these outliers was surprising, especially with Anyamal Tantei Kiruminzoo, a children’s anime about anthropomorphic magical girls with themes of ecological concern and friendship. Another one of these anime was Chikyuu Bouei Kazoku, which, unlike Kiruminzoo, Kawamori plays a much bigger part in besides just creating the original concept for. Having played a huge role in the script-writing for Chikyuu Bouei Kazoku, I was surprised to learn that this was Kawamori’s ...

"The Only Way To Save This Family Is For Them To Save The World"

The Daichis is one of those series that is so obscure and easy to overlook despite the fact it even got licensed and fully dubbed into English you would be forgiven for not having heard of it. It was this obscurity and ultimately curiosity that led me to watching the show and I'm so glad I did.

So airing in 2001 and animated by Group TAC The Daichis is a series about a family teetering on the edge of oblivion. We have the obese computer obsessed Father Mamoru, the equally work obsessed Mother ...

This proved to be a fun title. The Daichis serves as a parody of sorts of the sentai genre with the dysfunctional chemistry of the titular family as they get forced into becoming battle suit-powered "superhumans" to combat alien threats. The family issues of the family are explored both humorously and seriously where father Mamoru is a weak-minded otaku too spineless to stand up for himself, wife Seiko is too self-centered and greedy to care for her family's well-being, daughter Nozomi is stressed from doing all the housework for her family and son Dai is quite the problem child. Their unique circumstances as Earth's guardians ...
