Daigo is short.

The second cours of Major 2nd has expanded the story to give more depth to the supporting characters following the first cours' focus on Daigo (Goro's son) and Hikaru (Toshiya's son). As viewers familiar with the original Major might expect, this includes making initially hostile teammates more receptive to the new kids now that they're proving themselves on the field. This does mean revisiting themes about putting expectations on the children of superstars, but it also includes said children showing up kids who didn't know who they up against.

Damn, these two got old.

Major 2nd does give a lot of attention to its new characters' heritage and there are frequent appearances by characters from the original series. For example, three of the current coaches we've seen thus far have played baseball with Goro. (Okay, four, technically.) Although this is not to say that Major 2nd is dominated necessarily by characters with direct ties to the original Major. Most of the players we've seen so far don't appear to have any connection to characters from the first series.

It's Major. Maybe her parents will die.

Notably, Sakura Mutsuko, Daigo's classmate and the only girl on the Dolphins, is turning out to be an exceptional player in her own right. Initially just someone who sort of tagged along, there have always been hints that she's much better at baseball than anyone realized. Now that she's actually applying herself, it's obvious that she can effortlessly hit for contact, and apparently she's fast on the basepaths, too (legging out a triple on her first base hit). Really, it's just a matter of time before we see her taking people deep, making ridiculous catches in right field, and gunning down opponents who dared to round third. It's an odd thing to speculate about considering how much of the manga is probably already out, but I rather prefer not knowing how things develop for Mutsuko for the time being.

AE3803 doesn't quite know her way around yet.

One of the more pleasant surprises of the Summer 2018 anime season is Hataraku Saibou (Cells at Work!) which anthropomorphizes a human body's blood cells and depicts them as industrious workers carrying out tasks such as ferrying oxygen to different parts of the body and fighting germs.

You get used to it, newbie.

It's maybe about what you might expect if you're familiar with these sorts of gimmick shows, but the execution is quite good. The setup is suitably clever, and the various characters are endearing. In particular, Hanazawa Kana is excellent as the newbie red blood cell, AE3803. I enjoy her panicky shrieks. They contrast nicely with her white blood cell friend's somewhat staid approach to executing bacteria.

Platelet is also a fan favorite already.

I'm not sure how long this will stay amusing, but there's certainly no shortage of different stories the show could explore. There are at least five volumes of the still running manga, and three spinoffs, so I'm fairly confident there will be enough source material to keep the show entertaining throughout the season. In fact, Hataraku Saibou briefly held the top stop in my Summer 2018 ranking (until the incredible first episode of Shoujo☆Kageki Revue Starlight raised the barre). I'm not expecting Cells at Work! to remain quite this high for the rest of the quarter, but it is off to a strong start.

The matching guitars are actually magic beam rifles. This is not a joke.
P.S. Spoilers.

Seven or eight of the shows I plan to watch during the Summer 2018 anime season are shows continuing from Spring 2018 or sequels. Specifically, Overlord III, One Room 2, and Cinderella Girls Gekijou 3rd Season are sequels, and the shows continuing from last season are Detective Conan, GeGeGe no Kitarou, Major 2nd, Hugtto! Precure, and possibly Piano no Mori.

Maybe she has PE first period?

After two strong anime seasons, I'm mostly ambivalent about the upcoming Summer 2018 season. The shows I'm most interested in (Overlord III, Major 2nd, and Hugtto! Precure) are all either sequels or continuations of existing shows. Thanks to the sheer volume of anime that comes out each season now, I'm sure I'll find plenty of acceptably amusing titles to watch, but I'm otherwise merely mildly optimistic about the synopses I've read and the PVs I've watched.

I can't claim these are the most memorable Cures of the franchise.

Hugtto! Precure is about a quarter of the way through its (presumably) year-long run, so we should have a pretty good sense as to what sort of Pretty Cure it is. In contrast with its predecessor, Kirakira☆Pretty Cure à la Mode, Hugtto! is notably more violent. At least there is significantly more melee in the fights again. This was immediately apparent in its first appearance during the crossover cameo at the end of the Kirakira run, as that series quite obviously avoided direct punching and kicking—probably more so than any other Precure generation thus far. (Kirakira sure was happy to lean way into the emotional trauma side of things, though.) In any case, the return of fancy beatdowns is a welcome development.
