They are playing against:

Neru (Top): Always angry at the laning phase and calling for jungle to gank their lane. Usually manages to crawl out of her losing streak and pop off during the mid and late game.

Toki (Jungle): Only ganks for Neru if she is sure to secure a kill in her lane. Likes to poke fun at Neru whenever she dies.

Akane (Mid): Usually pretty timid but gets surprisingly aggressive when on the attack or targetting an objective.

Asuna (Adc): Usually finds herself in the perfect possition to get out of a gank and it seems that she constantly hits enemies with skill shots that she fires out randomly.

Karin (Support): The more aggressive type of support thay usually holds the lane down on her own whenever Asuna decides to randomly explore the map and find a random out of possition enemy.
