Re: Beat Blade Haruka (Alicesoft - Official English Release)
The second heroine starts with a quite high energy score, so it's easy to get right off the bat two skills, for example, to avoid traps in the dungeon, and always get items in the chests.
That means this particular gal has an easy way to become much stronger fast, since once you get the third dungeon skill she will avoid enemies, traps, and always open chests. It's useful for a first run, if you don't want to think too hard.
AFAIK routes were six, four good routes (harem + three heroines), two evil routes (the two main heroines with the MC as evil), but it's been a while since I last played it, so I don't recall correctly.
