Happy Hypoxia, Sayaka Mogi's manga, ends after several months

Happy Hypoxia, Sayaka Mogi's manga, has reached its final chapter. The publisher announced it officially, closing a publication run that began in June 2025, so the work says goodbye after several months in the pages of its magazine.

The news confirms there will be no new installments of the series. For those following the story chapter by chapter, this means a definitive ending and time to turn the page, never better said with a title about lack of oxygen.

An ending that arrives with no details on the volumes

The serialization of Happy Hypoxia kept a regular release pace since its start. Now, with the series finished, the next natural step would be the collected volume format, a process that requires reorganizing the published pages and adjusting the chapters for a continuous read.

The publisher has not detailed how many volumes will collect the complete work, nor has it given release dates. That's the part left up in the air after the ending announcement.

A farewell with barely any time to grow attached

Sayaka Mogi's readers have barely had time to learn the characters' names and it's already time to say goodbye. The series started in June 2025 and ends a few months later, a period that for some readers will have passed faster than a real hypoxia.

The question remains whether the ending was planned from the start or whether the author simply looked at the calendar and decided that was enough. Either way, a short story has its upside: you can reread it in an afternoon.
