On the 26th, Seibu Lions announced that they would hold six regular season games at Belluna Dome from April 28th to May 6th as a "Family Festival." At the same time, they also announced that they would hold "Pokémon Baseball Festival 2026" during the games against Softbank Hawks from May 4th to 6th.

pitcher Chihiro Sumida (26), who grew up familiar with Pokémon from a young age, enthusiastically commented through the team, "Congratulations on the 30th anniversary of Pokémon! I'm really looking forward to this event featuring the Pokémon I've been playing with since I was little. When I heard that The Lions' team partner Pokémon was 'Furious,' I thought it was an interesting match for the lion. By the way, my favorite Pokémon is 'Infernape,' which is also a fire-type like 'Furious!' During the event, we'll be handing out original The Lions Pokémon T-shirts and holding events where you can interact with Pikachu, so please come to Belluna Dome!" On the opening day, the 4th, original The Lions Pokémon T-shirts will be distributed to visitors. Furthermore, Pikachu will be "visiting" Belluna Dome through the 6th, with "Pikachu Welcome High-Fives" scheduled for pre-game and "Pikachu High-Five! Base Running" events planned for junior high school students and younger every day after games.
