This might be a shitty April Fool's Day joke (like seriously it's Haruhi episode 0 levels of purposely bad, good job!), but seeing Shamiko imagining being domestic with Momo for 2000 years really made me feel good inside.
Considering this is the group that makes the little goofy extras each chapter I was not surprised there'd be an april fools joke. But I really appreciate the happy april fools on page 1
