He is a very muscular person with rather full lips and brown, spiky hair.
His costume consists of a yellow full-body suit that has two holes for his mouth and hair to come out. He wears white gloves and boots and a utility belt around his waist.
Rikido has an interest in sweets and baking, the latter being a useful skill to have due to his Quirk. He is surprisingly talented at making sweets, conquering his classmates with his food. The fact that Rikido was caught off by this overly positive reaction suggests that he himself doesn't think much of his own abilities as a confectioner.
He is paired up with Koji by the lottery. It's unknown how well they both did in the trial itself.
Rikido places 15th in the Obstacle Race, allowing him to participate in the next event, the Human Obstacle Race. He then teams up with Toru, Kyoka, and Koji. Rikido fails to advance to the tournament event of the Sports Festival due to his team not accumulating enough points to advance.
Rikido along with his class watches the closing ceremony of U.A.'s Sports Festival.
Two days after the Sports Festival, Rikido is in class. During the Hero Informatics period, Class 1-A has to decide on Hero names. Rikido writes down and shows his classmates his Hero name: Sweet Taste Hero Sugar Man (甘味ヒーロー・シュガーマン Kanmi Hīrō Shugā Man?).
After Class 1-A is finished formulating their Hero names, Rikido is given a list of 40 work places in order to choose a workplace that he wants to train at. On the day of the work place training, Rikido is at the train station with his class so that he can travel to the work place of his choice by train.
One week before the end of term test, Rikido talks to Koji about the end of term test, saying that it will be more difficult than the mid-term tests. On the day of the exercise test, Mr. Principal reveals that Class 1-A will be fighting U.A.'s teachers in their exercise test.
Rikido is paired with Eijiro and they must face Cementoss in their test exercise. Rikido, Eijiro, and Cementoss arrive in an uninhabited city where their test exercise will take place. Cementoss explains the 30-minute test; Rikido and Eijiro must either handcuff him or one of them must escape the battlefield within 30 minutes in order to win and pass the test. The test begins.
Eijiro and Rikido keep smashing their way through Cementoss' cement walls, but the more walls they destroy, the more walls Cementoss creates to keep them at bay. Cementoss tells Eijiro and Rikido that their weakness is drawn out battles and advises the duo to push their strength to the limit. Eijiro and Rikido are unable to get past Cementoss' walls by the time the End of Term Test finishes, and as a result, they fail.
Back in class at U.A., Rikido is crestfallen that he is unable to go to the forest lodge due to failing the practical test Soon, Shota enters the classroom and informs Class 1-A that all of them are going to the forest lodge which will be a boot camp, which makes Rikido happy. However, Rikido will be receiving harsher training at the boot camp for failing the practical test. Rikido along with his class go to Kiyashi Ward Shopping Mall to buy necessities for the forest lodge.
The next day after the shopping trip, at U.A., Shouta informs Class 1-A that the destination for their lodge trip has been changed and the new destination will only be announced on the day of the event. The first semester has come to a close and summer break has begun.
On the day of the event, Class 1-A boards a bus that will take them to the forest lodge destination. An hour later, Class 1-A's bus stops for a restroom break. However, Class 1-A notes that Class 1-B is not at the rest stop. Suddenly, two females wearing cat-like costumes and a small boy appear; the females excitedly introduce themselves as the professional Hero Team, The Pussycats. Mandalay explains to Class 1-A that they will be staying at the base of a mountain which is a part of their domain; they have three hours to reach the base of the mountain using their Quirks as they please and those who do not arrive there by 12:30 pm will not be served lunch. Soon, Class 1-A realize that they have already arrived at their destination and their training camp has already begun with the Pussycats being their supervisors. Some of Class 1-A try to leave, but Pixie-bob uses her Quirk to create a landslide of dirt that causes Class 1-A to fall into a forest called Forest of Magic Beasts, which they must traverse to reach their destination. Suddenly, Class 1-A are confronted by a beast; Kouji tries using his Quirk to control the beast but it does not work due to the beast being made out of dirt. Izuku, Shoto, Tenya, and Katsuki mobilize and use their Quirks to destroy the dirt beast.
After Izuku, Tenya, Shoto, and Katsuki destroy the dirt beast, Class 1-A begins traversing the Forest of Magic Beasts. However, the journey through the forest to the Cabin takes around about 8 hours. Class 1-A arrive at the facility, battered and tired. It is now 5:20 pm in the evening. Pixie-bob admits that she thought they would take longer to get to the facility; she praises Class 1-A for figuring out her Earth Beasts quickly and easily.
Class 1-A fetch their luggage from the bus and put it in their rooms. Class 1-A go to the dining hall to have dinner. After finishing eating dinner, Class 1-A go to the hot springs. The next day at 5:30 AM, Class 1-A are outside the training camp cabin. Shota greets his students and tells them that they will undergo reinforcement training to strengthen and upgrade their Quirks which will also allow Class 1-A to obtain their temporary licenses.
At U.A. High School, Class 1-A along with Sato choose to make a band and dance performance for the U.A culture festival.
