Item description:

This is my Platinum Save Set for Dragon Quest Heroes: Yamiryuu to Sekaiju no Shiro or ドラゴンクエストヒーローズ　闇竜と世界樹の城,
action RPG in musou style (Dynasty Warriors), mixed with the characters and monsters from Square Enix's Dragon Quest series.
Interesting, grindy but not boring. Easy, but Post-game bosses can be challenging.
Unfortunately, western release was confirmed exclusively for the PS4, so the PS3 users have Japanese version only (shame on you SE). Use this site - DQH Wiki to translate skills, accessories, quests and other stuff (really helpful).
Start a New Game, follow the story for 駆けだしの親衛隊長 and エルサーゼの親衛隊 trophies.
At first you need to RESIGN saves with your own Profile. Don't forget to remove PARAM.SFO_ORIGINAL files. For testing on dummy accounts i used Bruteforce Save Data and everything worked perfectly - platinum.
