It requires four people in the same class to become a proper party, but their man is still climbing up the ranks, so they're left waiting.
Sakura, Erin, Shiro and Yuki are a group of new adventurers. They just entered the adventuring guild and was graded as A class adventurers, except for Yuki who's graded as class D. Meaning, he won't be able to enter their party, his own harem, without ranking up to A. And unfortunately for him, a lot adventurers are already gunning to the now unattended harem he left behind.

=Sakura=
The mage of the group. She's pretty meek and shy but very talented. She can be a clutz sometimes but she always tries her best to own up to it. She often gets harassed due to her voluptuous body, she attracts a lot of guys due to how cute and sexy she is, and a lot of those guys wants to protect her and be her "knight in shining armor". She's a sweet and innocent woman who have no sexual experience, nor her lips been taken yet, makes you wonder what Yuki has been doing all this time or if he's really interested in her.
=Erin=
Erin is the Knight of the group, she wields both sword and shield and is a master of positioning and timing. She's very playful and friendly, very easy to approach and nice to talk to. She have a heart of gold and walks the righteous path, she stand to those who can't protect themselves and always help people in need. Though she can be gullible sometimes, it's one of the reasons why she's always the first one to fall into traps and put into an unexpected situations. She's not dumb, she just trust people too much.
=Shiro=
Shiro is the Support of the group, the Healer, and the Tactician. Compared to Erin, she's pretty smart and doesn't trust people as quick as she does. She always see people, especially men, as lower beings who don't have the rights to talk to her nor approach her. She doesn't really like strangers and would avoid them as much as possible. Shiro is also very quiet and never really talk much unless she needs to, she's almost a complete opposite of Erin, except she's also very righteous and protects those who can't protect themselves.
