[News] [Tomo-chan is a girl!] https://sai-zen-sen.jp/comics/twi4/tomochan/ … Thank you for your visit. We will be closed from Sunday, March 31, tomorrow. The next month will be posted in April. In the next episode, Tomo-chan is a girl! Will be the last time. Thank you so much for your support to the end.
That is the Microsoft translation of the hiatus. I suspect what it means is that sometime in April, the manga will restart, and this will be the final leg before the end.
That said, his track record isn't so good for keeping to the announced timing on hiatuses. But this is free entertainment, and worth more than what we are paying for it.
