Shingo Komoi's Big Lesson!! (目指せVF甲子園！小茂井流大特訓！ Mezase Bui Efu Kōshien! Komoiryū Daitokkun!, "Aiming for the VF Koshien! Komoi-style Serious Special Training!") is a clan event in Cardfight!! Vanguard ZERO, first introduced in September 2020.
The event is similar to Character Fights, where you fight Shingo Komoi multiple times to get Monthly Vanguard and Murakumo Coins.
Instead of using stamina, the event fight uses Challenge Ticket: Shingo Komoi, which can be acquired by winning Character Fights. Each Character Fight grants 3 tickets, in addition to ticket reward upon every new day.
"Vanguard Monthly Magazines" are then used to play on the event-exclusive gacha, which only includes Murakumo cards.
Very Hard fight is only available once per day, need 0 tickets to enter, and only grants x10 as a reward for winning.
Auto-fight and Quick Fight options are available at all times, while in Very Hard mode, the Quick Fight option can only be unlocked after winning three times.
In both Japanese and Global versions, the card "Stealth Fiend, Oboro Cart" is not included in the gacha as it is intended to be. In response to this, said card was later granted at four copies in the players' Gift Box, while those who have already crafted it have received x50 for each copy owned.
