So, I read through the trial. There may be spoilers here, but since it's just the prologue, I don't consider them as such.
It started by introducing everyone in rather quick succession. That took a while, actually, considering the sheer number of characters. Naturally, the new ones had a little more time dedicated to themselves.
The humour continued in just the same pace and flavour as eariler, so that's all good. I especially like how no one really cares that there are clones, other than the regular idolising, but that's more because they're pretty girls than clones of famous people. In a strange world, people are used to strange things.
There's also the standard case of (almost) everyone new being impossibly strong, which raises the standard to even more absurd levels. It's not even certain Momoyo is on top anymore.
The new cast (of selectable girls) is interesting, and follows the general structure of the series, although with about once exception, they're kind of similar. Dark-haired fighters with personalities ranging from drunk to Yamato Nadeshiko
, and some happy in-between. Now, the exception is the little girl, Momoshiro, who's Hideo's little sister. She's introduced as someone who's been spoiled to the heaven, and she knows it. Naturally, as she is younger (she skipped grades), she does have a childish side, but the surprising part is that she actually seems very reasonable and charismatic, to the point where she's at least on the same level as the rest of the cast, if not above average in maturity. Definitely above Wanko and Chris, and possibly Mayucchi (who's in the same grade).
I think there were two endings in the prologue. One, like most non-standard endings, was with Miyako, and one, much funnier, happened when Chris
told him to "read the mood". That was such a shock to him the game ended right there, after a brief but hilarious ten-year-later epilogue.
