Umamusume Mihono Bourbon and Twin Turbo Support Card Debut

Cygames’ first Umamusume: Pretty Derby update went out, adding a Mihono Bourbon Trainee and Twin Turbo Support Card to the game. To help people decide if these would be banners worth pulling on, it shared detailed information about both the character and card. 

Mihono Bourbon is a Trainee who, without any additional Inheritances, is best at running Medium distances on Turf tracks. She also only works with Front strategies. She’ll also develop Power and Stamina at higher growth rates of 10% and 20%, respectively. Her Unique Skill is called G00 1st F∞. It’s designed to work with the Front Runner strategy by letting her increase velocity in the final straight. Depending on improvements you make once getting her, she can also learn the Skills Front Runner Straightaways, Taking the Lead, Front Runner Corners, and Trackblazer during a Career. The first three all pertain to her Front strategy, while Trackblazer helps her recover during Medium races if she’s in first. 

As for the Twin Turbo: Turbo Booooost SSR Support Card, it is a Speed card. Through events, you could get the Front Runner skill Taking the Lead to learn. It also offers a Turbo Boooooost effect that increases mood effect and race bonus. Her other support effects include 20% Friendship Bonus during Friendship Training, an Initial Friendship Gauge 25 bonus for Friends during Careers, and Mood Effect 60% bonus when training together with a Friend Support Card.

Here’s how both of the infographics for the new character and card look:
