大星 淡

Awai is a first-year at Shiraitodai High School. She is recognized as a successor of Teru Miyanaga and one of the monster-class first-years that could beat even veteran third-years along with Saki Miyanaga. She was able to climb into the regulars' team just in a month. Due to her skills and abilities, Awai is considerably confident, cocky, and arrogant, but is shown to be the most talkative and cheerful out of her Shiraitodai teammates. She seems fairly close to Teru and is pretty attached to her, calling her by her first name without any honorifics, which is somewhat unusual outside of close friends.

Awai has two abilities, a passive one and an offensive one. Her passive ability is called "Absolute Safety Zone" - this makes her opponents start off with hands that have a low probability of completion, normally hands with 5-6 shanten. The following draws are normal, however. This ability can only be beaten by abilities that manipulate a player's own starting hand. Her second ability is also her most offensive and dangerous one. With this ability, she can declare a double-riichi but her hand has no other yaku in it.  Also, just before reaching the last corner in the wall, she will declare a concealed kan and will almost always win immediately after rounding the corner.  Should she win with this ability, it will be revealed that the kan she made will be comprised of at least four kan doras radically increasing her score.  With this ability she also seems to be able to get a direct-hit on one of her opponent's.
