Sasaki to Pii-chan

Two MC's who are able to teleport from Earth to their Isekai worlds whilst bringing in goods from Earth in order to make money, both characters studying something, whether it's combat or magic, in order to assist them on their journeys. There is a fair lot of action between the two whilst both MC's meet an array of people on the way. Perhaps the biggest difference is that Rougo is more focused on its Isekai setting as opposed to Sasaki where there is a balance between the two worlds. 

Using teleport to isekai to make money by selling japanese goods 

Our MC's have the hability to travel from one world to another and they want to acquire gold by selling normal articles here who are very complex in comparation with the technology from the world of magic and fantasy. They are a good entertainment. 

- Both MC can travel back and forth from Earth and the isekai fantasy world - Both MC sell modern Earth consumer goods to isekai world for gold to exchange for Earth currency - Both have isekai denizens amazed by the Earth goods, attracting the attention of nobles and royalty - Both MC start getting entangled in economic politics, and political politics. - Both animes has firearm usage "Saving 80,000 Gold in Another World" follows these premises a lot more, is more character and comedy driven, and actually goes somewhere by the end of the season. Whereas "Sasaki and Peeps" threw in a lot of mismatching things which deviated everything from these premises quite often, thus never really delving too deep into things nor characters, and the season ended feeling like it never really went anywhere, and also on a cliffhanger.  read more 

Same mood and layered magic styles with Mechs as extra 

Similarities: Both Sasaki to Pii-chan and Hinamatsuri explore a sense of reverse isekai where the main characters enter the modern world from a fantasy one. They depict protagonists who find themselves navigating unfamiliar environments and societal norms vastly different from their original worlds. This transition serves as a central theme in both series, highlighting the protagonists' adjustments and interactions with modern-day settings. Differences: Sasaki to Pii-chan focuses on economic strategies and interdimensional trading as the protagonist navigates business challenges across different worlds, emphasizing entrepreneurship and the integration of modern knowledge into societal frameworks. In contrast, Hinamatsuri follows a yakuza member who discovers a young girl with supernatural powers and ends up becoming her guardian. The series humorously explores the protagonist's unconventional parenting experiences while balancing comedic elements with poignant character development. Both series provide engaging narratives that play with the concept of reverse isekai, offering unique perspectives on adaptation, relationships, and personal growth in contrasting worlds. read more
