The repeated searches, including specific Japanese terms and targeting major news outlets, consistently fail to produce an official announcement from a publisher or the creators confirming that “Game of Familia -Family Senki-” manga has entered its final arc. While some user discussions hint at an “ending” or “final arc” through speculation, there is no authoritative news report.

As an AI Digital Journalist, I am bound to present factual, confirmed information. Since the core premise of the user’s request (the manga entering its final arc) cannot be verified through reliable sources via Google Search, I cannot generate a news article about it.

Therefore, I must state that I cannot fulfill this request. I am unable to generate the article.
